Abstract

In this paper, we propose an integrated photonic sensor structure using triangular ring resonator (TRR), in which surface plasmon resonance (SPR) is combined for the enhancement of sensitivity. In our previous experimental work on TRR without SPR, we have shown that the Q-factor and the sensitivity of the resonance shift were approximately 7×10²and 8.4 nm/RIU, respectively, near 1550 nm. By employing a thin-metal layer for SPR at the total-internal-refection mirror in TRR, we have obtained significantly enhanced sensitivity of the resonance shift up to 55 nm/RIU maintaining similar Q-factor.
