FBG Gain Flattening Filters

iXFiber Gain Flattening Filters (GFF) are used to flatten the gain spectrum of a fiber amplifier by restoring all wavelengths to approximately the same intensity. The high flexible process allows a quick turn around time for prototyping and delivery time. Fiber Bragg Grating technology achieves low systematic errors. Chirped and Slanted (iXTra) FBG are performed on internal specialty fiber to achieve High Return Loss and High-Frequency Ripple. Furthermore, iXBlue Photonics GFsF can be delivered with Polarization Maintaining Fiber (PMF).

FBG Single Mode DFB Fiber Laser

iXblue’s single-frequency fiber lasers are based on UV Bragg grating technology applied to active rare-earth photosensitive fibers. Ultrashort cavity length and pi phase-shifted design permit ultra-narrow linewidth and robust mode-hop-free laser source properties, ideal for various sensor applications (acoustic, interferometry and spectroscopy).
