| Research Abstract |
We have done research on control of lasing states of semiconductor lasers and their application to optical information processing, in order to realize the core routers where optical signals can be buffered without converting to electric signals. We have realized unidirectional ring lasers and semiconductor optical isolators with high On/Off ratio by applying nonreciprocal propagation characteristics to semiconductor lasers. These research results are useful for optical isolators integrated with semiconductor lasers and their application to optical information signal processing.
