Abstract (in Japanese) (See Japanese page) 
(in English) As a potential method in reducing the cost and power consumption of over 100-Gigabit coherent links, there is an increasing interest in utilizing the state-of-polarization of light more efficiently beyond the simple polarization multiplexing. In this work, we propose novel monolithically integrated Stokes vector modulators, which consist of waveguide-based polarization converters and polarization-dependent phase modulators in simple straight-line configurations. The proof-of-concept devices are fabricated on InP by employing the half-ridge InP/InGaAsP polarization converters and electro-optic phase modulators. We experimentally demonstrate polarization modulation over the two-dimensional surface of the Poincaré sphere. With relatively simple fabrication and compatibility with other waveguide components, the proposed modulators should easily be integrated with other active components to offer potentially low-cost monolithic transmitters for the Stokes vector modulation formats.
