title: Zinc-diffused two-dimensional optical waveguides in n-type GaAs.
abstract: Two-dimensional waveguides were fabricated in n-type GaAs by zinc diffusion. Experimental observation of the dependence of waveguide cutoff on channel width agrees with theoretical models of the refractive index profile.
