Ultra-Low Crosstalk and Fabrication-Tolerant Silicon-Nitride O-Band (de)Multiplexer Using Bragg Grating-Assisted Contra-Directional Coupler

Ultra-Low Crosstalk and Fabrication-Tolerant Silicon-Nitride O-Band (de)Multiplexer Using Bragg Grating-Assisted Contra-Directional Coupler

A wavelength division (de)multiplexing (WDM) filter with ultra-low channel crosstalk (XT) and high tolerance was proposed for a 1 × 4 O-band coarse-WDM (CWDM) system on a silicon-on-insulator (SOI). The filter consists of four waveguide Bragg grating (WBG) structures, each one having a mu...
