Kylia Optical Assembly Expertise, Now Integrated into Exail
A leading provider of advanced free-space micro-optical assembly solutions, now integrated into Exail.
Kylia brings compact, reliable micro-optics solutions at Exail
With over 20 years of expertise and technical know-how, Kylia brings to Exail its capability to design state-of-the-art free-space micro-optical assemblies that meet the demands of the most critical environments, including space deployment.
Kylia know-how includes the integration of complex optical functions (power splitters, combiners, optical switches, frequency shifters, etc.) in micro-optical modules, turning a complex optical setup into a compact, ultra-stable package, combining miniaturization and high performance. These turnkey fibered benches offer excellent alignment stability over a wide temperature range.
Transforming large photonic experiments into micro-optics assemblies is ideal for applications requiring precision and reliability, such as quantum technology, QKD, LiDAR, and space communications. Thanks to their innovative design, micro-optical technologies simplify installation while delivering high performance even under extreme conditions.
About Kylia
Founded in May 2003, Kylia is the former optical division of Photonetics. The Kylia team of experts in micro-optics is driven by ex-managers from Photonetics (later acquired by NetTest, then Anritsu).
Kylia R&D leverages in-depth knowledge in optic design and packaging to develop robust and smart solutions for optical manipulation of light. The combination of human know-how, state-of-the-art design tools, and precise instruments allows us to offer high-performance optical assembly for industrial applications.
Kylia’s technological expertise is built on precise “free-space optics” and bulk-grating assembly using 6-axis nano-positioning of micro-optical elements to rapidly develop and customize advanced optical functionalities such as interferometry, polarization beam manipulation, wavelength multiplexing and fiber coupling.
For two decades before joining Exail, Kylia contributed its optical assembly expertise to a range of French and European institutional projects focused on advancing high-bit-rate optical networks, coherent detection, metro and wideband telecom systems, multimode fiber propagation, secure and high-capacity transport, OFDM radio-over-fiber technologies, and novel sensing applications such as holographic submarine acoustic detection.
Leading Free-Space Micro-Optics Solutions
State-of-the-art micro-optical assemblies for coherent detection, demodulation, multiplexing, signal and delay control
Kylia’s expertise enables the design and manufacturing of integrated micro-optics for advanced photonics architecture, for laser, quantum, space and telecom applications.
MUX/DEMUX
Optical Multiplexers (MUX) and Demultiplexers (DEMUX) are foundational components in modern fiber-optic networks, designed to maximize bandwidth efficiency through Wavelength Division Multiplexing (WDM). A MUX combines multiple optical signals of different wavelengths into a single fiber for transmission, while a DEMUX performs the inverse operation at the receiving end, separating the combined stream back into individual channels.
COH
The 90° Optical Hybrid (COH) is a fundamental passive component in coherent optical communication and sensing systems. It is designed to extract the phase and amplitude of a signal by mixing an incoming signal with a Local Oscillator (LO). This process creates four distinct interference states with 90° relative phase shifts, enabling the retrieval of the full complex envelope of the modulated light.
iMOB
Custom solution to turn a complex optical setup, like a quantum computing setup, into a compact module
VODL
Variable Optical Delay Lines (VODLs) are essential components in high-precision photonics, designed to provide fine-tuned control over the optical path length. By adjusting the physical distance light travels, these devices enable the synchronization of optical signals with sub-picosecond accuracy.
MINT
The Micro-Interferometer (MINT) is a specialized DPSK (Differential Phase Shift Keying) demodulator designed for high-bit-rate optical communications. By utilizing a delay-line interferometer (DLI) structure, the MINT converts phase-modulated signals into amplitude-modulated signals, allowing for precise data recovery at the receiver end.

Micro-optical Assemblies Expertise at Exail
Exail leverages Kylia’s expertise in six-axis micro-positioning to deliver unmatched assembly precision and repeatability. Each optical component is actively aligned with sub-micron accuracy, drastically reducing error margins. They meet the most rigorous industry requirements for reliability and performance.
Using real-time active alignment, we ensure each component is precisely positioned and permanently bonded. This method guarantees optimal optical coupling, minimizes insertion loss, and removes the need for post-assembly adjustment or cleaning.
Our team develop optical products in assembly epoxies, built to be used in extreme environments as EOM subsystems. We can lead or be part in all the product development steps.
Exail selects the most suitable assembly materials, including adhesives and substrates, tailored to the specific environmental conditions of each application. They are chosen to ensure optimal performance, reliability, and durability of the assemblies, even in the most demanding environments.
By combining those various expertise, Exail (formerly Kylia’s) team, can help you shrink your laboratory, to turn a complex experiment into a compact and robust system. The micro-optical benches can be customized at will to meet a great variety of optical designs, including stringent optical specifications.
