Abstract: Optical waveguide isolator (121) for monolithic integration with semiconductor light emitting diodes such as Fabry-Perot or ring laser diodes. The present optical isolator (121), with optical input port (95) and output port (96), comprises a branching waveguide coupler (56). This branching waveguide coupler (56) has a waveguide stem (60) splitted at one end into two waveguide branches (57,58) such that a light wave fed via said input port (95) into a first of these branches (58), is guided via the waveguide stem (60) and the output port (96) out of the device. A light wave fed to the isolator's output port (96) is guided along the stem (60) and coupled into the second waveguide branch (57) to the absorber (54).

Abstract: Disclosed is a method for efficient and self-aligned laser to waveguide coupling being an important step towards higher integration of opto-electronic circuits. For automatic alignment of an optical waveguide (67 - 69) to a ridge waveguide laser (50 - 52), the ridge structure (54) of the laser is transferred into the substrate (50) by etching the mirror groove. The transferred ridge structure (55) serves as base for the deposition of the waveguide layers (67 -69), their thickness being controlled during the deposition such that the waveguide core (69) is laterally and vertically aligned to the lasing active layer (51) of the laser structure (50 - 52).
