Metallic Grating Couplers – Broadband and Efficient
conference on lasers and electro optics（2021）
摘要
Metallic grating couplers can be extremely broadband and efficient. In this work, we investigate an all-plasmonic fiber-to-chip coupler with a coupling efficiency of -2.7 dB and an optical 3-dB passband of 300 nm.
