Abstract
An optical waveguide amplifier is formed to include an adiabatic region disposed between an input single mode waveguide and a large area, multimode gain region. The utilization of the adiabatic region allows for a single mode signal to be supported and provides for a larger gain area to be formed, thus providing a larger gain and higher output power than conventional prior art waveguide amplifier arrangements.
