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.

The optical signal transmission system includes one or more optical wave guide switches (11 to 15) for switching between transmission paths for transmission of light signals and an optical level adjusting device (16 to 24) connected with the one or more optical wave guide switches in at least one of the transmission paths. The optical level adjusting device (16 to 24) controls its own light transmittance with a thermooptic device (22,24) and the one or more optical wave guide switches (11 to 15) switch between transmission paths by a similar thermooptic device (14,15). The one or more optical wave guide switches and the optical level adjusting device are arranged in an integrated thermooptic circuit in a common substrate.

Proposed is an integrated optical component, particularly a modulator, directional coupler, switch, polarizer, distributor or the like, as well as a method of producing such a component. The component has a light waveguide (17) of an optical polymer which is disposed on a silicon substrate (10) that has at least one optical buffer layer (14) having a low refraction index, wherein a positioning trench (12) that is anisotropically etched into the substrate (10), is essentially aligned with the light waveguide (17) and has a V-shaped cross-section is provided for receiving a glass fiber (11) to be coupled to the coupling end surface (18) of the light waveguide by means of end-to-end coupling. The positioning trench (12) is filled with a plastic material (15) at the end region on the coupling side, wherein the light waveguide (17) extends on the plastic material (15) up to an end surface (18) of the plastic material (15) which extends perpendicular to the axial direction of the light waveguide (17) and lies in the plane of the coupling end surface. This end surface (18) is disposed outside of a diagonally-extending end region (13) of the positioning trench (12). The end surface (18) and thus the coupling end surface can therefore be created in a simple manner by means of laser machining processing, in which the established technology for producing the positioning trench by means of anisotropic etching can be used.
