Claim Text:
1. A semiconductor laser apparatus, comprising: a silicon-on-insulator assembly; and an edge-emitting semiconductor laser assembly integrated on the silicon-on-insulator assembly; the silicon-on-insulator assembly comprising an optical waveguide at the top which is bonded to the edge-emitting semiconductor laser assembly and configured to couple a laser light emitted from the edge-emitting semiconductor laser assembly, wherein the optical waveguide comprises: a core portion located in the middle of the optical waveguide; and at least one vertical rib configured on two sides of the core portion respectively, with a width narrower than that of the core portion, wherein the edge-emitting semiconductor laser assembly comprises a simple Fabry-Perot (FP) Broad Area (BA) laser, a Distributed Bragg Reflector (DBR) laser, a Distributed Feedback (DFB) laser, or a Quantum cascade laser (QCL), and the edge-emitting semiconductor laser assembly comprises the DFB laser which comprises at least one row of DFB gratings disposed on a top surface of the core portion along the length direction thereof.
