Abstract

We have proposed a novel biosensor scheme based on a dual photonic crystal microcavity with a stadium-shaped ring resonator (PCM-SSRR) and characterized the resonance conditions for the first time. The Q of the dual PCM-SSRR was significantly enhanced when a single PCM or a dual PCM was in the same resonance condition with the SSRR. We demonstrated a mutual interference between the dual PCM. In this study, the Q of the dual PCM-SSRR was increased three times over that of the directional coupler structure used with the single PCM. Assuming a detectable spectral resolution of 10 pm, a refractive index resolution of 3.03×10^-5 can be achieved on the dual PCM-SSRR.
