We propose, analyze and demonstrate a side-coupled Fabry-Perot (F-P) resonator filter composed of two dissimilar waveguides with π phase-shifted Bragg grating. The resonance circuit is formed by t…
We present a new configuration of narrow linewidth semiconductor lasers (NLSLs) based on a novel narrow-band reflector (NBR) with π phase-shifted anti-symmetric Bragg grating (π-ASBG). Based on t…
We proposed a new kind of add-drop multiplexer based on π phase-shifted antisymmetric Bragg grating ( π-ASBG). Light resonance is formed in the π-ASBG with mode conversion between backward funda…
