ABSTRACT:
The invention relates to a method for producing an optical transmitting and receiving device (1, 1a) comprising a light emitting transmission element (3, 3a) and a receiving element (4, 4a) which converts this light into an electrical magnitude. The transmission and receiving elements are inserted into a silicon substrate. The optical transmitting and receiving device (1) is preferably inserted in a monolithic manner into a common substrate, comprising a sequence of superimposed layers for the light emitting transmission element (3) and the light receiving element (4). An electrically insulating intermediate layer (9, 9a) is incorporated between the transmission and receiving element.
