Patent ID: 7522648

Claim:
A hybrid type integrated optical device, comprising: a semiconductor laser including a first structure having an active region and a light emission surface formed on at least one side surface of the first structure, and a second structure formed below the first structure and having upper surfaces exposed at the light emission surface of the first structure and at a side surface opposite to the light emitting surface; and a planar waveguide platform including a substrate, a lower clad layer, a core layer, an upper clad layer, being sequentially stacked in this order on the substrate such that some region of the substrate is exposed, and a metallic pattern formed on the exposed region of the substrate, wherein the semiconductor laser is flip-chip bonded to the metallic pattern, such that the exposed upper surfaces of the second structure contact a recessed region of an upper surface of the upper clad layer of the planar waveguide platform and remain partially exposed.
