On-Chip Arrayed Waveguide Grating Fabricated on Thin-Film Lithium Niobate
Zhiwei Fang, Min Wang, Ya Cheng and co-workers have fabricated an on-chip 8-channel thin-film lithium-niobate arrayed waveguide grating (AWG) by using photolithography-assisted chemo-mechanical etching technique (see article number 2300228). On-chip loss as low as 3.32 dB, a single-channel bandwidth of 1.6 nm, and a total-channel bandwidth of 12.8 nm are obtained. The cross talk between adjacent channels is measured to be below –3.83 dB and the cross talk between nonadjacent channels is below –15 dB.
