ABSTRACT:
A composite optical device having a high efficiency of coupling a laser diode and an optical device and a method of producing the composite optical device. The composite optical device connects a laser diode with a first mesa including an active layer on a (001) plane of a compound semiconductor substrate via a first cladding layer and an optical device provided with a second mesa including an optical waveguide layer formed on the (001) plane via a second cladding layer, wherein one end of the active layer and one end of the optical waveguide layer oppose each other at a distance smaller than the thicknesses of the first and second cladding layers. At least the second cladding layer is grown in an ambient supplemented with HCl to produce a planar surface.
