| Research Abstract |
The increasing speed and power consumption in optical telecommunications has focused attention on all-optical signal processing. The aims of this study are the measurement of the ultrafast transient response of the polarization switching in the polarization bistable VCSEL, the clarification of the mechanism of the polarization bistability, and the designing the structure of the VCSEL which aimed in the high speed operation. So, I improved the VCSEL structure for the high speed and the low-power consumption operation. I also investigated the measurement system of the ultrafast switching and the applied system for the optical communication using the VCSEL.
