Multi-wavelength fiber laser based on broadband fiber grating and HiBi fiber loop mirror

Abstract:

A fiber laser based on broadband C-band fiber grating (CFG) and high birefringence (HiBi) fiber loop mirror (FLM) is demonstrated,which uses the comb-like reflection performance of the HiBi FLM. Under different polarization states,different output lasers are gained by choosing the polarization states of the light in the cavity using the polarization controller.By this method,a single wavelength or dual wavelength laser beam can be output,and multi-wavelength oscillates can be achieved.
