<p>Provided is an alignment method of a semiconductor optical amplifier (200) with which optimization of coupling efficiency between incident laser light and light waveguide of the semiconductor optical amplifier (200) is enabled without depending on an external monitoring device. The alignment method of a semiconductor optical amplifier is a method that optically amplifies laser light from a laser light source (100) and outputs the optically amplified laser light, which adjusts relative position of the semiconductor optical amplifier (200) with respect to the laser light entering into the semiconductor optical amplifier by flowing a given value of current to the semiconductor optical amplifier while entering the laser light from the laser light source (100) to the semiconductor optical amplifier (200) so that a voltage applied to the semiconductor optical amplifier becomes the maximum.</p> |
