Abstract

In the case of the above devices, exact adjustment is very important; however, the devices ought to be very compact. It is not sufficient to utilize the silicon etching technique for the precision. The optical transmitting element (LD) is situated on a first carrier (T1), the optical receiving element (PD) and the transmission fiber (Fa) are situated on a third carrier. Provided in between them is a second carrier (T2) which is transparent to the wavelength of the light emitted by the transmitting element (LD). The carriers are structured by means of anisotropic etching in order to make possible the accommodation of the individual components. In addition, the carriers lie flat on one another and can thus be adjusted. A monitor diode (MD) is provided. Application of the arrangement in all transmission systems having optical waveguides.
