| Outline of Final Research Achievements |
SOI MOSFET single-photon detector features low dark count at room temperature, photon-number resolution when multiple photons enter at the same time, and low-voltage operation. In order to make the detector practical, performances are improved from the view points of light receiving area, quantum efficiency, and operation speed, and the following results are attained. (1) Increase of the light receiving area and quantum efficiency by the use of surface plasmon (SP) antenna, (2) Reduction of noise and hole lifetime by the substrate bias control, (3) Clarification of the requirements for high-speed operation through the output signal simulation and the investigation of signal processing method, and the realization of the real-time digital signal processing, (4) Realization of fast read out by RF reflectance method, and (5) World first demonstration of photon detection and the improved quantum efficiency by the use of FinFET.
