Wroclaw University of Science and Technology
The station allows for fabrication of Bragg gratings in optical fibers. Thanks to the use of two different inscription methods: “point-by-point” and through the phase mask, it is additionally possible to fabricate Fabry-Perot interferometers based on Bragg gratings, as well as to introduce modifications of Bragg gratings (chirped gratings, tilted gratings, pi-shifted gratings), required depending on the targeted applications. The use of femtosecond laser allows for fabricating of gratings in silica fibers (also without the need to remove the protective coating), in planar waveguides, and fluoride fibers for applications above 1.5 μm.
