Microwave Photonic Filter Using Multiwavelength Brillouin-erbium Fiber Laser with Double-Brillouin- Frequency Shift

摘要

A microwave photonic filter based on double-Brillouin-frequency spaced multiwavelength Brillouin-erbium fiber laser (BEFL) is experimentally demonstrated. The filter selectivity can be easily adjusted by tuning and apodizing the optical taps generated from the multiwavelength BEFL. Reconfiguration of different frequency responses are demonstrated.
