ABSTRACT:
A method of altering a refractive index, as for an optical waveguide, as in a buried heterostructure laser, by inducing disordering in a region of a semiconducotr body comprises exposing a surface portion of the semiconductor body to plasma etching, coating at least a part of the surface portion with an oxide layer, heat treating the semiconductor body.
