- Chirped FBG
Due to a variation of the refractive index modulation within the FBG along the fiber, an optical chirp of the wavelength is generated. This FBGs have a broad bandwidth of several nm and a flat top profile instead of the typical Gaussian shape. Typical applications are WDM 1300/1550nm band rejection filter, ASE filtering, noise suppression or in-fiber mirrors.
- Wavelength locker, laser diode stailizers (LDS)
A very common application of FBGs is the stabilization of DFB laser modules. They are applicable to pump lasers for EDFAs 980/1480nm as well as for WDM modules for the 1300/1550nm band. Typical applications include also in-fiber resonators for RAMAN fiber lasers or tunable laser modules.
- Wavelength selective filters for telecommunications
FBGs are widely used in optical communications as in-fiber narrow band filters, e.g. for DWDM technology for 2.5 Gbps and 10 Gbps systems, ASE filtering or Add/Dropmultiplexers for 100GHz and 50GHz channel spacing. Fiber Bragg Gratings provide highly selective wavelength filtering with low insertion loss, making them ideal for dense wavelength division multiplexing (DWDM) and optical signal processing. Their precise reflection characteristics enable stable and efficient spectral shaping in fiber optic networks.
- Fabry-Perot cavities
The fiber Fabry-Perot Interferometer is a pair of matching FBGs. In this case an extremely small phase shift can be detected; for sensing purposes and to evaluate small vibrations or acoustic signals. By coating the fiber between the gratings with an electric, magnetic or acoustic enhancing coating small changes can be measured.
- FBG for dispersion
FBGs can be designed to introduce customized dispersion profiles, effectively compensating for chromatic dispersion in long-haul optical communication systems. This ensures improved signal integrity, reduced pulse broadening, and enhanced transmission performance.
- FBG for lasers and amplifiers
FBGs play a crucial role in laser stabilization by acting as narrowband reflectors, ensuring precise wavelength locking for high-performance fiber lasers. They also facilitate mode-locking in ultrafast laser systems, enabling the generation of stable and high-quality pulse trains for advanced applications.
- Working wavelength
We can adapt telecom products usually working at 1550nm to other wavelengths: 780nm, 980nm, 1064nm, 1310nm, 2000nm… These adaptations facilitate their use in instrumentation setups, high power sources, sensing applications, metrology, and interferometric measurements.
- Tailored pigtails
We offer customized pigtails with options including fibers (SM,MM, PM, PCF), lengths, buffers, jackets, and connectors such as FC, LC, SC and SMA among others.
- Specific packaging
We offer specific packaging solutions tailored to the needs of our customers into slots, racks, modules… This enable us to deliver OEM products that are ready for seamless integration into their systems. Moreover, our team always considers environmental factors such as temperature, humidity and vibration to ensure the stability and reliability of optical components in varying operating conditions (passivated athermal packaging, phase conservation, and optical path balancing).
- Optical optimization
Through precise simulation, modeling, and iterative design processes, we optimize key parameters such as transmission efficiency, beam quality, polarization characteristics, and spectral properties. This optimization ensures that our optical components deliver superior performance, reliability, and consistency in diverse optical systems and applications.
