We investigated the feasibility of biosensing for a novel two-dimensional (2-D) photonic crystal (PC) based nano-ring resonator by computational study. The photonic crystal is composed of periodic hexagonal hole array on a silicon plate. A hexagonal nano-ring resonator is arranged in between two silicon PC waveguides. This PC nano-ring resonator is packaged in a fluidic channel, while analytes flow via a sensing hole will be trapped. Due to the absorbed analytes in a particular hole along the hexagonal ring, the output resonant peak wavelength shifts to longer wavelength region. The sensitivity of various holes has been studied.
