Abstract(in Japanese) (See Japanese page)
Abstract(in English) Semiconductor optical amplifiers(SOAs)in array configuration are attractive for applications to optical parallel interconnection systems as optical loss compensators.For those applications,SOAs have no gain sensitivity to input signal polarization.In order to exclude the sensitivity,one should form a bulk active layer which width and thickness are both less than about 5000Å.However it is d ifficult to form such a narrow width of active layer uniformly and reproducibly by conventional methods with semiconductor etching.In this report,autors realized to form such narrow width of active layers uniformly by employing newly developed selective MOVPE technique which does not need semiconductor etching.And the quthors realized 1.3μm wavelength SOA arrays.In a 4-channel array, each SOA has more than 20dB of signal gain and less than 1dB of polarization sensitivity.
