March 2010 : Kylia introduces integration-ready coherent receivers
Kylia has developed an integration-ready coherent receiver. The optical system is compatible with OIF recommendations and is dedicated to components manufacturers focused on RF/photodiode side willing to propose an integrated coherent receiver.
The 8 outputs are free space and can be directly coupled into four pairs of balanced photodiodes. The geometry of the outputs (beam size, pitch etc…) can be user defined. Kylia can also take in charge the integration of the coherent receiver in front of the photodiodes. “Providing optical complex subsystems to RF/photodiode components based manufacturers will give them access to 100 Gbit/s market”, says Frédéric Verluise, CEO of Kylia.
“Delivering the dual polarisation coherent receiver in the most advanced optical laboratories around the world has been our contribution to make the DP-QPSK format jump from paper study to real 100 Gbit/s experiments. Offering the integration possibility is our next participation to make DP-QPSK format a reality in the existing optical networks. ”, says Jacques Clermont, sales Manager of Kylia.

September 2008 : Kylia's DLI are integrated into U²T 40G DPSK receiver
u²t Photonics AG, a provider of innovative, leading edge optoelectronic components for fiber optic systems, unveiled its IDRV series as first product of its new product platform of integrated optical receivers supporting higher order transmission formats such as DPSK or DQPSK. 
The new product series comprises u²t's well established balanced receiver technology in combination with Kylia's delay line interferometer technology based on free-space optics. The compact new receiver eases the design of DPSK systems by reducing the foot-print of the optical front-end and avoiding the critical fibre routing and component matching required when using discrete components. Transponder and system manufactures are enabled to build smaller form factor sub-systems and therefore to further reduce size, power and cost of 40 G systems.
The product has been specified in close cooperation with leading transponder and line card manufacturers and it will be offered in different variants and with optional features allowing for special customer requirements. 
In order to quickly develop this new product generation and to support the fast growing demand the two companies entered into a cooperation earlier this year and are working closely together utilizing both companies' know how, expertise and strengths in the most efficient way. Kylia's free space optics technology is used in a variety of stand alone products such as delay line interferometers for DPSK applications and 90° Hybrids for coherent detection. u²t's balanced technology is widely used in the DPSK deployment. 
Both companies are committed to complete this new development and to finish qualification early 2009.  
"This integration between so different technologies is now possible thanks to leaps forward in the micro optic assembly process domain", said Frederic Verluise, Kylia's CEO , "Now this innovative integrated optical receiver opens the door to many compactness-driven complex optoelectronics modules such as integrated coherent receivers"
"With flexibility on both sides we have achieved an amazingly fast progress in our joint activity", said Jens Fiedler, VP Sales & Marketing at u2t, "resulting in provision of this new platform just at the time of DPSK technology transition from line card to transponder solutions. It will help to significantly reduce our customers' design effort, to save board space and to obsolete fibre routing between DLI and balanced receiver."
u²t announced the availability of prototypes of its new product platform starting now. The IDRV series is targeted for volume production in the first half of 2009 and will offer a price benefit against the discrete solutions when delivered in volume.

Today, Kylia has references in the telecommunication and space domains.”

June 2008: Kylia launches single ended coherent receiver
Kylia today simplifies and lightens coherent reception architecture.
Kylia proposes a coherent receiver to get rid of balanced photodiodes.
Single ended photodiodes will be used to convert optical signals into electrical waveforms.
Saving balanced photodiodes will make installation easier and less expensive.
Kylia uses four outputs over the eight available on the COH28.
As for standard COH28, the input signal is polarization spitted and the LO is spitted 3dB.
Each polarization signal is mixed with the LO for a total of four outputs.
Each output is offset from the previous one by 90°.
The robust architecture of Kylia component allows a high power handling.
Powering significantly the Local Oscillator in comparison to Signal simplifies equations
and allows recovering incoming Signal phase and amplitude with four outputs instead of eight.

May 2008: Kylia exhibits coherent receiver for PDM-QPSK
Kylia today emphasizes its coherent receiver advantages in Polarization Division Multiplexed Quadrature Phase-Shift Keying application.
Polarization Division Multiplexed Quadrature Phase-Shift Keying is today seen as the most promising solution to move to higher rate up to 100 Gbit/s.
Its high tolerance to linear fiber effects makes PDM QPSK a perfect candidate for new modulation format.
At the receiver end, a coherent receiver is needed for reading PDM-QPSK.
The Kylia coherent receiver (COH28) is a dual-polarisation coherent mixer.
COH28 mixes a signal with a Local Oscillator and exhibits four output ports per polarization.
Each port is offset from the previous one by 90°.
Knowing Local Oscillator amplitude and Phase, COH28 allows the recovering of Signal characteristics.
Totally passive, COH28 can reach a typical offset precision up to +/- 1°.
COH28 supplies the in-phase and in-quadrature along all the C+L band.

Dec 2007 : Kylia unveils polarisation diversity optical hybrid
The polarisation diversity 90° hybrid so called COH28 is aimed to compute absolute phase
and amplitude of the signal independently of the polarisation.
Main features of the product are passive phase difference stability over OTR and over wavelength range.
COH28 inherits from COH24 a time adjustment between input and In-phase output or Quadrature output of 0.1 ps.
“COH28 is today the only polarisation diversity optical hybrid available on the market.
COH28 is the logical upgrade of COH24. COH28 allows reading data encoded in both polarisation of the optical field” says Frederic Verluise, technical manager.

Dec 2007 : Kylia goes ultra-fast DPSK demodulator
Kylia today launches an ultra fast version of DPSK demodulator. Kylia extends its micro-interferometer range mint-1x2.
A piezo actuator ensures a time constant of 0.1s for compensation of very quick signal frequency variation.
For comparison, the today market proposes time constant not shorter than 5 seconds.
The ultra fast version will be packaged into the same package than standard DSPK demodulator: 50 x 42 x 12 mm. Standard tunable mint-1x2 is controlled by a voltage of 0-5V in order to actively tune the delay.
For both tunable versions, the delay tuning allows a frequency shift of one FSR (Free Spectral range).
Mint-1x2 shows an impressive accuracy along the entire C band.
Finally, the ultra fast version inherits from the all mint-1x2 family of an incomparable optical path delay between receiving ports of 0.1 ps.
Thanks to its very low PDFS, the combination of two mint-1x2 is an ideal candidate for DQPSK demodulation.

Nov 2007 : Kylia narrows DWDM Space
Kylia today delivers athermal Mux/Demux with 12.5 GHz spacing in volume.
Benefiting of the flexibility of the Bulk Grating Technology,
Kylia always proposed DWDM Mux/Demux for grid narrower than the ITU one.
Thanks to its athermicity aspect, Kylia mics met an immediate success into submarine network
with spacings between 25 GHz and 50 GHz.
Frederic Verluise, Kylia CEO said “Our technology always gave us the possibility
of meeting the submarine network requirements in terms of spacing and athermicity.
In addition, we have always been proposing spacing underneath 25 GHz for lab application.
We today met a market allowing us to deploy 12.5 GHz Mux/Demux on large quantity.
We are now working the same way with multiplexers of few GHz spacing for lab application and we will be.

Oct 2007 : Kylia unveils DWDM Mux/Demux tunable in Frequency
Kylia today enlarges its DWDM Mux/Demux range with mics +.
Directly affiliated to the standard mics,
mics + allows not only to Multiplex/Demultiplex a Dense Wavelength combo
but also to tune this combo on a very large frequency band.
A mics + with a nominal spacing of 100 GHz has a frequency tuning range of 800 GHz.
This feature makes mics + ideal for compensating Laser frequency drift in an optical network.
In addition, with the same channel count,
mics + allows to run its networks test/experiments along eight different ITU grids.
Frederic Verluise, CEO of Kylia said: “With mics +,
We fully benefit from advantages offered by free space technology.
By letting one piece of optics free of movement, we give a new flexibility axe to the final customer
without deteriorating the optical performance.
Some of our customers found new applications we did not think about first
and it is more than likely that we will discover some others in the future.”

Oct 2007 : Kylia launches interferometer for bidirectional amplification
Kylia declines its standard micro-interferometer mint 1x2 into a micro interferometer with two inputs and two outputs,
so called mint 2x2. mint 2x2 offers the possibility of a bidirectional amplification with a standard amplifier.
An application drawing is available online.
mint 2x2 allows the integration of a “one-way” path at some point of a bidirectional fibre , hence enabling amplification.
Afterwards, even and odd channels take back their nominal directions towards the two different edges of the fibre.
mint 2x2 is a wavelength interleaver directly issued from the mint 1x2. mint 2x2 inherits of outstanding performance of the mint 1x2.

Oct 2007 : Kylia delivers DWDM Mux/Demux on S band
Kylia widens its frequency range for DWDM Mux/Demux up to S band.
Kylia has always been delivering Mux/Demux on bands C & L. Kylia today offers a new way of upgrading an existing DWDM network with S band development.
“We have always offered S band Mux/Demux on customer request for lab application or specific industrial cases.
We now jumped to an industrial step by fully equipping a complete part of our production facilities.
This capacity of converging from a lab request to an industrial deployment in a short time is the result of a policy which has always lead Kylia.
” Said Frederic Verluise, CEO of Kylia.
