ABSTRACT:
A semiconductor optical device and an optical device array is provided which can be used in an optical logic circuit, photonic switching OEIC, etc. The device includes a light amplifying arrangement 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, by virtue of providing a light amplifying means in addition to the light deflecting portion, noise components are not amplified, and, therefore, the SN ratio is markedly increased.
