We demonstrate all-optical flip-flop operation of Mach-Zehnder bistable lasers with falling time of less than 68 ps. The device can be controlled with continuous 58-nm wavelength range of input light.
We fabricate and experimentally demonstrate all-optical flip-flop switching based on novel Mach-Zehnder interferometer bistable laser structure. The MZI-BLD successfully acts as set-reset flip-flop with continuous light injection.
The author's group has been trying to establish fundamental technologies necessary for "digital photonics," by realizing optically-controlled digital photonic devices and circuits based on artificial optical properties of semiconductors, including digital wavelength converters, optical 3R repeaters, optical logic gates, optical dynamic memories, and integrated optical isolators. In this...
We demonstrate a bandgap-engineered dynamic monolithic MZI SOA all-optical switch with wide stripe selective area MOVPE. Compared with other simple laser-EAM integration with other bandgap engineering techniques, it is the largest working device ever achieved. All-optical wavelength conversion was achieved with single SOA all-optical modulation. In all-optical switching with differential phase technique,...
