Photo-inscription of Bragg gratings and waveguides in fibers and bulk glass using a femtosecond laser.
Quote on request
Our laboratory inscribes periodic structures into various types of optical fibers and transparent materials, based on silica or exotic glasses. It includes a Coherent Astrella laser system (4 mJ, 1 kHz, 30 fs), an automated inscription setup, an interferometric setup, spectral characterization systems covering 350 to 5500 nm, and Bragg grating modeling software.
