Optical head integrable on a hybrid circuit

Abstract

Abstract The invention relates to an optical head intended to be integrated on a hybrid circuit. <??>This optical head comprises at least one semiconductor electrooptic assembly (2+31+36) and an optical fibre (1) in alignment. With a view to transferring it onto a hybrid circuit, all the elements are attached to a metal plate (28) which serves as a reference plane. The fibre (1) is brazed or bonded onto the plate (28) by means of a metal tube (29) which supports a lens (30). If the head comprises a second electrooptic assembly (3+40), also fixed to the metal plate (28), a dichroic mirror or a semi-reflecting plate (41) reflects the light beam onto the second assembly (3). A filter (42) improves the separation of the light beams. <??>Application to optical couplers, multiplexers, demultiplexers and duplexes. <IMAGE>
