A channel waveguide optical amplifier (100) is disclosed. The amplifier includes a substrate (110) and an optical waveguide channel (120) disposed on the substrate. The optical waveguide channel includes a first (130) generally spiraling portion having a first free end (132) and a first connected end (134), a second (140) generally spiraling portion having a second free end (142) and a second connected end (144), and a transition portion (150). The transition portion has a first transition section (152) connected to the first connected end, a second transition section (154) connected to the second connected end, and an inflection between the first and second transition sections. The amplifier also includes a directional coupler disposed on the substrate proximate the first free end. An amplifier assembly incorporating the channel waveguide is also disclosed. |
