Ultra-Broadband Optical Filter Based on Step-Chirped Multimode Waveguide Bragg Grating

An ultra-broadband optical filter based on step-chirped multimode waveguide Bragg grating (SCMWBG) with low insertion loss, high sidelobe suppression ratio (SLSR), compact size and relaxed fabrication accuracy is demonstrated on SOI platform. The grating length of SCMWBG is divided into grating segm...
