| 摘要 |
An optical gate device transmits or interrupts input light according to control information. The optical gate device includes a light-receiver that obtains input and output optical powers of the optical gate device, and a monitor that obtains optical input and output characteristics of the optical gate device based on the control information and the monitored input and output optical powers, the optical input and output characteristics being equivalent to a time the optical gate device is controlled in a transmitted state.
