Abstract
A channel waveguide optical amplifier is disclosed. The amplifier includes a substrate and an optical waveguide channel disposed on the substrate. The optical waveguide channel includes a first generally spiraling portion having a first free end and a first connected end, a second generally spiraling portion having a second free end and a second connected end, and a transition portion. The transition portion has a first transition section connected to the first connected end, a second transition section connected to the second connected end, and an inflection between the first and second transition sections. An amplifier assembly incorporating the channel waveguide and a method of amplifying a light signal are also disclosed.
