We report a novel high-power bistable distributed feedback (DFB) semiconductor laser diode operating near 1060 nm, which is realized by inserting a high-bandgap electron barrier layer and Pain Relief a grating layer in a super large optical cavity laser design.Optical and electrical bistable characteristics are both observed for this Suction Canisters and Liners device.An on-state optical output power of 98 mW and an on-off extinction ratio of 22 dB were demonstrated between the bistable states.A qualitative physical model based on copyright population profile shift is used to explain the switching effect.

Optical flip-flop operation was also demonstrated.
