摘要：
We report the optical characterization of an InP structure constituted by waveguides coupled to microcavity disk resonators. The lateral waveg-uide confinement is obtained by deep reactive ion etching through the guiding layer. We demonstrate the possibility of tuning optically the resonance wavelength into the illuminating disk resonator. We obtained a blueshift of 3 nm by laser irradiation at 980 nm corresponding to a photoinduced change in the effective refractive index of 6 X 10(-3). The InP structure behaves as a tunable optical demultiplexer. (c) 2006 Optical Society of America.
