Abstract

A resonant cavity waveguide device structure is reported which incorporates a grating structure to couple the vertical incident light into the waveguide and uses Bragg grating to constitute a resonator. Two types of grating are fabricated simultaneously on a surface of thin Si waveguide to gain high sensor sensitivity for the refractive index change measurement.
