摘要

Optical switches are being developed utilizing the intersubband transition (ISBT) in nitride semiconductor quantum wells, for application to future ultrafast network systems. So far, the ISBT has been achieved at optical communication wavelengths and optical responses within a picosecond have been demonstrated. Moreover, the ISBT has been observed for a waveguide structure. Simulations were carried out utilizing the parameters obtained from the experiments. The results suggest that operation at 1 Tb/s could be achieved with a power consumption of less than 1 W. These results confirm the possibility of realizing optical switching devices.
