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 demonstrate a wavelength-tunable all-optical flip-flop (AOFF) based on a multimode-interference (MMI) bistable laser diode (BLD) with distributed Bragg reflectors (DBRs). The wavelength tuning can be achieved by the band-filling effect and the free-carrier plasma effect with carrier injections to the DBRs. The tuning range of 3.1 nm will enable flexible and reconfigurable design of future photonic...
We investigate wavelength tunability of all-optical flip-flop using distributed Bragg reflectors. Single-mode lasing and flip-flop switching is obtained with more than 24.7-dB extinction ratio and 21.5-dB SMSR at 3.1-nm tuning range.
