Outline of Final Research Achievements |
The high-speed optical wavelength selective switch was fabricated with a hybrid integration of silica waveguide chips and a PLZT optical switch. It had 20 wavelength channels with 200-GHz spacing. The switching speed was less than 20 ns. We also fabricated a large-scale optical wavelength selective switch using multi-layered silica waveguides and LCOS spatial light modulators. It had wavefront compensation function and showed good wavelength switching characteristics. The photonic switching node architecture using a high-speed wavelength selective switch was proposed.
