Abstract

© 2020 IEEE.A rod-type silicon photonic crystal structure has been designed and numerically analyzed for the first time in a sensing application. Rods are sandwiched between Perfect Electric Conductor (PEC) plates to obtain 2D PhC characteristics. Light-matter interaction is maximized by strong light localization in the air region, cavity Q-factor is enhanced with Fano-like resonance, and an ultra-high sensitivity up to 1039 nm/RIU is observed.
