“…In addition, logic gates based on microring lasers [23][24][25][26][27] are also favorable devices for all-optical logic gates. However, many of the all-optical logic gates that have been reported and demonstrated thus far utilize switching in the lasing between clockwise (CW) and counterclockwise (CCW) directions [1,[28][29][30][31][32], and they are not necessarily suitable for cascade arrangements owing to spatial switching.…”

We experimentally demonstrate all-optical flip-flop and inverter operations using two adjacent lasing wavelengths in a quantum-well microring laser, and that the state is switched between the flip-flop and inverter operations by changing the phase in the outer cavity composed of busline waveguides. We also propose multimodal rate equations for a microring laser taking into account clockwise and counter-clockwise light propagations. By comparing experimental results and simulated results based on the rate equations, the principle of the switching between the flipflop and inverter operations is clarified.
