Abstract: The invention relates to a method of manufacturing an optoelectronic semiconductor device whereby two comparatively thin layers are provided next to one another on a substrate by means of a non-selective growing process, an etching process, and a selective growing process, a cladding layer being present over said thin layers. In the known method, first the one thin layer and the cladding layer are grown, the latter is locally removed, and the other thin layer and the cladding layer are then grown in that position. 
     This method has the disadvantage that unevennesses (steps or openings) often arise at the surface of the layer structure above the transition between the thin layers. 
     A method according to the invention is characterized in that in a first non-selective growing process the one layer and a small portion of the cladding layer are provided, these layers are locally removed in the etching process, and the other thin layer and a small portion of the cladding layer are provided in that location in the selective growing process, after which in a second non-selective growing process the major portion of the cladding layer is provided. The layer structure obtained has a substantially plane surface which is free from defects and is very suitable for further processing. The thin layers may be, inter alia, an active and a radiation-guiding layer. According to the invention, especially devices having a mesa structure can be manufactured with a high accuracy and yield.

Abstract: In plural channel amplifier systems processing many phase locked signals of different frequencies (on 111-114) as a combined signal (from 106), these signals may drift into a phase convergence causing a peak power occurrence in the amplifier (109) which greatly exceeds the rates capacity of the amplifier system. Therefore, in accord with the invention, a dynamic adjustment system is provided to minimize the peak power to which the amplifier (109) is subjected by adjusting (by means of 131-134) the relative phase relationships of the many signals. The dynamic adjustment system includes a peak power detector (153), a hard wired logic decision circuit (161) and a timing control (161) to control phase shift adjustment steps (on 171-174).

Abstract: The invention relates to a tanning apparatus which comprises a couch, an illuminator and, where appropriate, a face tanning apparatus which form a tanning tunnel, UV radiation being transmitted from the interior of the couch, of the illuminator and, where appropriate, of the face tanning apparatus, into the tanning tunnel. This tanning device is to be improved in such a way that there is hardly any waste heat on the body, it does not necessitate cooling of the apparatus and manages with a reduced connected load. This is achieved in that there is a central radiation generator which is arranged remote from the radiation emergence surfaces delimiting the tanning tunnel, and in that the central radiation generator is connected to the interior of the couch, of the illuminator and, where appropriate, of the face tanning apparatus via fibre optical waveguides which project from the wall sections of the couch, the illuminator and, where appropriate, the face tanning apparatus, opposite the radiation emergence surfaces, each end of the fibre optical waveguides being allocated to a device which causes the emerging bundle of rays to be distributed over a large surface area with uniform distribution of the radiation.   <IMAGE>
