We report on the switching times and energies of a DFB all-optical flip-flop and their dependence on device and operating parameters. Numerical as well as experimental results are discussed.
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.
We have demonstrated all-optical packet switching, in which an MMI-BLD optical flip-flop worked as a label memory. The optical flip-flop allowed self-routing of multiple-wavelength packets with 338-ps switching time and 14-dB on-off ratio.
First-ever integrable all-optical flip-flop multi-mode interference-DBR bistable lasers are demonstrated. 1550 nm-based flip-flops SET/RESET at -3/-5 dBm injection, switch over a 52 nm-range (1522-1574 nm) three times wider than previous reports, and will be useful for future optical memories.
Regenerative wavelength conversion was obtained using multimode interference bistable laser diodes and cross gain saturation in semiconductor optical amplifiers. A digital transfer function of wavelength conversion was achieved through the optical flip-flop thresholding function
