  • Optical waveguide amplifier using a circulator and an optical signal reflective surface and method employing same
    Publication number: 20030156792
    Abstract: An optical amplifier with integrated optical waveguide, pump source and other, optional components for amplifying an input optical signal. The amplifier includes a circulator and an optical signal reflective surface disposed at an end opposite an optical signal input receiving end of the waveguide which enables an optical signal to pass through the waveguide a second time exposing the optical signal to further amplification. The disclosed amplifier offers cost advantages and a higher gain without sacrificing other performance characteristics.
