FemtoFBG is a laser micromachining workstation optimized for fiber Bragg gratings (FBG) writing.
It is a perfect choice for scientific laboratories, R&D centers, and industrial clients working with telecommunications, distributed sensors, and Bragg Grating based devices development.
Femtosecond FBG writing is a proven technology for universal Bragg Gratings writing in various optical fibers, including not UV-sensitized fibers.
The main advantage of femtosecond laser writing is the ease of process tuning compared to a process using a UV phase mask.
Femtosecond lasers can be applied for Point-by-Point (PbP) and Line-by-Line (LbL) writing for up to 2nd order FBGs writing in various optical fibers, including multicore fibers. The smallest pitch in PbP writing is ~1 µm.
