| Research Abstract |
A fast and self-holding optical gate switch that use phase-change material, which is usually used for DVD media, was proposed and fabricated. The length of the switch was only 10 microns and the switching time was less than 100ns. We developed a tunable dispersion compensator, successfully demonstrated dispersion compensation of about a 50-km standard optical fiber, and regenerated the degraded transmitted optical signal. We also proposed and fabricated an arbitrary optical spectrum controller, which had a grid-less transmission characteristics suitable for controlling an optical modulated signal.
