摘要

Component of the laser emission to vertical cavity surface emitting at a wavelength between 1,3 and 1,55, comprising a stack having two mirrors (2, 6) which is reflected at the wavelength of emission and one or more layers (4) which are interposed (s) between these two mirrors (2, 6) and which constitute an amplifier medium of the emitted radiation, characterized in that at least one (2) of these mirrors present in the vicinity of the amplifier medium (4) a layer (2a) of alx ga1 - x as, for x included between 0,8 and 1, selectively oxidized (2ai and 2aii) around an active central area of the amplifier medium (4). br / in the process of the invention, are grown epitaxially two samples on an inp substrate, the other on a gaas substrate and the two samples thus obtained by epitaxial adhesion of a layer of gaas of the second sample on an inp layer of the first, the sample thus obtained is then etched, and then oxidized by hydrolysis.
