An integrated optical device having at least two optical devices integrated therein and a method of fabricating the integrated optical device are provided. To fabricate an integrated optical device having optically connected and electrically isolated first and second optical devices on a substrate of a first conductive type, an active layer and a clad layer of a second conductive type are first formed in a mesa structure on the substrate, an SI clad layer is then formed on the substrate surrounding the clad layer of the second conductive type and the active layer, and finally first and second conductive layers are formed into trenches by diffusing a dopant of the second conductive type into the SI clad layer in areas corresponding to the first and second optical devices.

Integrated optical device and fabricating method thereof

An optical apparatus having a vertical light receiving element is disclosed. The optical apparatus is configured to couple light generated from a light source using the vertical light receiving element, then transforms the received light signals into an electric signal. The optical apparatus includes: a vertical photo detector having a photo-absorption layer; and an optical bench on which the photo detector is disposed. The optical bench having a first groove and a second groove formed adjacent to each other, the first groove having a predetermined inclination and being formed at an edge of a first surface of the optical bench, and the first surface being opposite to a second surface of the optical bench, on which the photo detector is disposed, such that a light signal incident to the first groove is refracted at a predetermined angle by the first groove; and the light signal, which has been refracted by the first groove, is totally reflected by the second groove. As a result, that the light signal is substantially and vertically incident into the photo-absorption layer.
