Fibre Bragg Grating for Fibre Laser

FBG(Fibre Bragg Grating) produced by YOFC is a periodic refractive index modulation in optical fibre core through UV exposure which can achieve the modulation of signal light in optical fibre. It is an indispensable part of a high power fibre laser.
Applications
