    摘要: In a method of fabricating a surface-emitting laser, to assure good electrical confinement and good flatness of the mirrors defining the resonant cavity of the laser an electrical confinement layer is formed by carrying out the following steps: forming an undercut layer, at least one growth step on the undercut layer, forming a mesa defining the shape and the location of the top mirror and exposing the undercut layer on its vertical walls, and controlled lateral etching of the undercut layer. Applications include the fabrication of a semiconductor laser on a III-V (e.g. InP or GaAs) substrate.

    摘要: To avoid the phenomena of self-focusing and astigmatism of the amplified wave, the amplifier includes in succession: an input segment having an input waveguide adapted to guide a monomode input wave; a diffraction segment comprising a first medium transparent to said monomode input wave and adapted to widen it; a collimation segment; and an amplification segment having an amplifier waveguide wider than said input waveguide. The amplifier can provide a high-power laser source supplying a widened fundamental mode wave. Application to producing waves for pumping fiber optic amplifiers.
