ABSTRACT:
Disclosed are a planar wave guide type optical amplifier for amplifying a light signal passing through an optical fiber, a method of manufacturing the above light amplifier, and a laser oscillator using the light amplifier, The planar wave guide type optical amplifier comprises a first core formed to a bar shaped on a substrate and a light amplifying region composed of a part of the first core, having a configuration extending to the longitudinal direction of the first core, and doped with a rare earth element. The method of manufacturing the planar wave guide type optical amplifier comprises the steps of (1) forming a bar-shaped core on a plane substrate, (2) forming a groove to the core which extends to the longitudinal direction thereof, (3) filling the groove with a filler doped with a rare earth element and (4) solidifying the filler. The laser oscillator comprises a first core formed to a bar shape on a substrate, a light amplifying region composed of a part of the first core, having a configuration extending to the longitudinal direction of the first core, and doped with a rare earth element, and light reflecting means provided with the opposite ends of the first core, respectively,
