So many things you can do with tilted fiber Bragg gratings (TFBG)….

A quick look at publications from 2019-20 so far....  First, for work done entirely or mostly at Carleton: Fu Liu's PhD thesis deals with all optical dynamic effects obtained by putting active coatings on the cladding surface of tilted FBGs.  His first paper in APL Photonics describes GHz rate all optical modulation of a...
