Abstract
In the case of the above devices, accurate adjustment is very important; the devices ought, however, to be very compact. It is not sufficient to utilize the silicon etching technique for accuracy. The optical transmitting element (LD) is located on a first holder (T1), and the optical receiving element (PD) and the transmission fiber (Fa) are located on a third holder. Provided there between is a second holder (T2) which is transparent to the wavelength of the light emitted by the transmitting element (LD). The holders are structured by means of anisotropic etching in order to render it possible to receive the individual components. Furthermore, the holders lie flat on one another and can be so adjusted. A monitor diode (MD) is provided.
