Abstract:Objective Among the many photonic devices, the Bragg grating of chalcogenide glass fibers is important. As a linear device, it can be applied to infrared sensors. In nonlinear optical applications, it can achieve alloptical signal processing. In addition, it is necessary to apply Bragg grating with high reflectivity to obtain efficient integrated chalcogenide glass fiber lasers, such as the distributed feedback Brillouin lasers. For chalcogenide glass fibers, it is complex to write Bragg gratings, mainly becau… Show more
