Claim Text:
1. A method of manufacturing a superluminescent diode, the method comprising: forming a passive waveguide layer, a lower clad layer, an active layer, and a first upper clad layer on a substrate having an active region and an optical mode size conversion region; removing the active layer and the first upper clad layer in the optical mode size conversion region; forming a tapered waveguide region connected the active layer and the first upper clad layer on the lower clad layer in the optical mode size conversion region; forming a passive waveguide region connected tapered waveguide region; and forming a second upper clad layer having a mesa structure on the first upper clad layer in the active region, and surrounding the tapered waveguide region and the passive waveguide region in the optical mode size conversion region.
