8-Channel CWDM Filter on the Lithium-Niobate-on-Insulator Platform Using Cascaded Multimode Waveguide Gratings
An 8-channel coarse-wavelength-division multiplexing device is realized on lithium-niobate-on-insulator platform. The experiment result exhibits box-like spectral responses with ~20 nm channel spacing, 1-dB bandwidth <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\sim$</tex> 13-16 nm, and low inter-channel-crosstalk <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$< -22\text{dB}$</tex> for all channels.
