| abstract | A first solution of the present invention is to establish a semiconductor optical amplifier having a high saturated light output and a stabilized gain that can be adjusted by an external signal for use in an optical system, and a method of manufacturing the same. It is. A second problem to be solved by the present invention is to realize an all-optical wavelength converter with a simple device configuration, small size, and high efficiency. Means for solving the above-mentioned problems in the present invention are as follows. First, in a semiconductor optical amplifier including a laser resonator structure, a laser oscillation light and an optical signal are formed by using an optical waveguide shared by the laser resonator structure and the semiconductor optical amplification structure as a multimode interference optical waveguide having a plurality of output ports. The amplified signal light was positionally separated. In addition, a region where the optical gain or optical loss is controlled by an external signal is provided in the region of the laser resonant waveguide where the optical signal of the semiconductor optical amplifier does not pass, and the laser threshold gain is changed to be completely independent of the laser oscillation light. In addition, the optical amplification rate can be controlled. [Selection diagram] Fig. 4 |
