Low-crosstalk and fabrication-tolerant four-channel CWDM filter based on dispersion-engineered Mach-Zehnder interferometers

Hongnan Xu et al.

Summary: A low-crosstalk and fabrication-tolerant four-channel CWDM filter has been proposed and experimentally demonstrated in this paper by utilizing dispersion-engineered Mach-Zehnder interferometers. The use of multi-sectional phase shifters and multi-mode waveguides helps to eliminate phase errors and inhibit random-phase errors, achieving ultra-precise phase shifts and ultra-large width-error tolerances. The two-stage-coupler scheme is utilized to flatten strong coupling-ratio dispersions for directional couplers, resulting in low crosstalk over the entire O-band.

Ziwei Cheng et al.

Summary: A high-order coupled-resonator optical waveguide (CROW) nanobeam filter with semi-symmetrical Fano resonance enhancement was proposed and experimentally demonstrated. The designed filter has high-contrast transmission, low insertion loss, compact size, high extinction ratio, and low insertion loss. Its passive structure eliminates the need for thermal control calibration on each resonator, making it a basic building block for various applications requiring high extinction ratio filtering.
