Ultra Compact Plasmonic Resonators for Optical Communication

This paper describes the performance of ultra compact plasmonic waveguide ring resonators (WRR) fabricated on a Cu-based waveguide using CMOS technology. A WRR with 2.59-mm radius exhibits excellent performances such as insertion loss of ~0.1 dB, extinction ratio of ~12.8 dB, free spectral range of ~47 nm, and quality factor of ~275. The small form factor and CMOS-compatibility of the proposed WRRs are highly promising for seamless integration of key building blocks in silicon based electronics photonics integrated circuits (EPICs) used in optical communication devices.
