All-optical tunability of InGaAsP/InP microdisk resonator by infrared light irradiation

Abstract

We report the optical characterization of an InP structure constituted by waveguides coupled to microcavity disk resonators. The lateral waveguide 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 6×10−3. The InP structure behaves as a tunable optical demultiplexer.
