ABSTRACT:
An optoelectronic coupling element having a light-emitting semiconductor device serving as transmitter chip, and a light-receiving semiconductor device serving as a receiver chip, and are firmly connected together through an optic coupling medium (3). This compact coupling element is to have a defined degree of coupling largely independent of the housing and is to be suitable for simple conductor tape mounting. To this end, the coupling medium (3) is an insulating transparent intermediate layer, and the light-emitting semiconductor device (1), the coupling element (3) and the light-receiving semiconductor device (2) are directly laminated one on the other. This optoelectronic coupler is used in particular as an optocoupler for signal transmission.
