Abstract:
A method of making a wavelength converter assembly, comprising:providing a substrate; forming an epitaxial structure on the substrate, wherein different areas of the epitaxial structure have different optical properties; forming a widely tunable edge emitting laser in the epitaxial structure, wherein the laser is comprised of in-plane integrated elements and wherein the laser generates an optical output; and forming a photodetector in the epitaxial structure, wherein the photodetector is comprised of in-plane integrated elemental and wherein the photodetector receives an optical input other than the optical output generated by the laser and generates an electrical signal in response to the received optical input that is used to modulate the optical output generated by the laser; wherein the laser and photodetector are laterally displaced from each other in the epitaxial structure.
