    摘要： A method for coupling a surface-oriented opto-electronic element, particularly, a VCSEL laser diode, an LED, or a photodiode, with an optical fiber and an opto-electronic element for carrying out such a method, the opto-electronic element having a rotationally symmetrical protruding structure disposed symmetrically with respect to the optically active zone of the opto-electronic element, includes the steps of wetting the butt of the fiber and/or the protruding structure of the opto-electronic element with a transparent adhesive, moving the opto-electronic element and/or the fiber toward each other such that a substantially frictionless movement of at least one of the element and fiber can occur, waiting for a self-centering of the fiber and the protruding portion; and waiting for or bringing about a hardening of the adhesive for purposes of fixing the now-centered configuration between the fiber and the protruding portion.

    摘要： In the case of a multiple semiconductor laser structure containing a plurality of laser pn junctions stacked vertically one on top of the other, different operating temperatures of the active zones occur during operation on account of the different distance within the layer structure from a common heat sink. The displacements in the emission wavelength caused by the temperature influence are compensated by a variation of the thickness and/or material composition of the active zones, so that a narrow wavelength distribution is achieved.

    摘要： A semiconductor laser arrangement for high output power in the lateral fundamental mode. A semiconductor laser region is provided in which a waveguide is provided for wave guidance, this waveguide being dimensioned such that the laser emission oscillates in the fundamental mode perpendicularly to its propagation direction. The arrangement has a coupling region, and an intensification region in which the lateral wave guidance is cancelled and is provided with a contact for current injection.
