摘要：
A semiconductor optical switch and an optical switch array for use in an optical logic circuit, photonic switching, OEIC, etc., wherein a light amplifying means is provided on a bypass waveguide that connects a plurality of optical waveguides, thereby enabling improvement of the light crosstalk and the light propagation loss. In particular, according to the arrangement of the present invention that a light amplifying means is provided in addition to the deflecting portion, no noise component is amplified and therefore the SN ratio is markedly increased.
