Abstract
A planar hybrid optical amplifier is fabricated on a single crystal substrate. The components that are common to a variety of optical amplifier circuits are mounted on the substrate and the planar device that results is readily interchanged in various applications. In one embodiment the multiplexed signal consisting of light from a pump laser and an optical signal are introduced into a rare earth doped fiber which amplifies the input signal through stimulated emission of radiation.
