| Outline of Final Research Achievements |
In this project, we aimed to develop novel devices to manipulate and detect the polarization state of light inside a semiconductor photonic integrated circuit. We first proposed and experimentally demonstrated that compact and efficient polarization modulators and polarization analyzers can be realized by monolithically integrating the half-ridge polarization converters with quantum-well-based modulators and detectors. By using developed devices, we also demonstrated high-speed decoding of multi-level Stokes-vector modulated signals. The developed technologies should have diverse applications including optical communication, sensing, and quantum computing.
