ABSTRACTThis paper is the first report of the use of Si+ implantation into GaAs/GaAlAs MQW material to form optical waveguides operating at a wavelength of 1.15μm. Lateral confinement is achieved by mixing of the MQW material which is produced by the implantation of Si+ and subsequent annealing at 750°C. The properties of these waveguides are compared with those of chemically etched rib waveguides and are shown to have reasonably low losses.

Tem Characterization

An optical waveguide consists of a several-micron wide channel with a slightly different index of refraction than the host substrate; light can be trapped in the channel by total internal reflection.Optical waveguides can be formed from single-crystal LiNbO3 using the proton exhange technique. In this technique, polished specimens are masked with polycrystal1ine chromium in such a way as to leave 3-13 μm wide channels. These are held in benzoic acid at 249°C for 5 minutes allowing protons to exchange for lithium ions within the channels causing an increase in the refractive index of the channel and creating the waveguide. Unfortunately, optical measurements often reveal a loss in waveguiding ability up to several weeks after exchange.
