Abstract
A high gain of 27dB is achieved in an erbium-doped silica-based planar waveguide amplifier integrated with a directional coupler which multi plexes the signal and pump light. A low noise figure of 5.0dB is attai ned with the planar amplifier by using an integrated coupler which is formed of erbium-doped silica-based waveguides.
