Dual-Layer SiNx-on-SOI Grating Coupler as an Efficient Higher-Order Fiber Mode Multiplexer (JW1A.178)

Presenter: Lirong Cheng, Tsinghua University

We demonstrate a dual-layer grating coupler as an efficient higher-order fiber mode multiplexer. Four channels from a fiber array can be multiplexed into four distinct TE-polarized modes in a few-mode fiber using the proposed multiplexer.
