ABSTRACT:
The invention concerns an optical guiding structure comprising, between two optical confinement layers, an optical guiding layer and an optical guiding element separated from each other by a layer for stopping chemical attack, to obtain by epitaxy methods and by chemical attack, a guiding element of which it is possible to precisely calibrate the thickness obtain surfaces of excellent quality and perform cutting out with sharpness, the invention being applicable to producing lasers and optical phase modulators.
