Waveguided optical switches using a carrier injection plasma dispersion are proposed. InGaAsP/InP four-port switches with two intersecting single-mode channel waveguides were fabricated by selective LPE and investigated at 1.5 ¿m wavelength. Optical switching was observed, based on mode interference in the waveguide intersecting region.
