FBG Filter of 50GHz & 1550nm

FBG Filter of 50GHz & 1550nm

Fiber Bragg gratings are widely used components in optical communications. FBGs act as narrowband filters in optical fibers. Bragg gratings are printed in optical fibers by a holographic process. They can be produced either with standard single-mode fibers or with special fibers, namely radiation-mode suppressed fibers used to reduce cladding mode losses.
