Abstract: A set-reset flip-flop of all-optical operation. A set light is inputted through a set port. Then, a multimode interference portion in a waveguide oscillates only in a set mode. As a result, a noninverted output Q is produced from a noninverted output port. Even if the input of the set light is turned off, the output state is maintained. When a reset light is inputted through a reset port, the multimode interference portion stops its oscillation in the set mode and causes oscillation in a reset mode. Thus, an inverted output Q-bar is generated from an inverted output port. Even if the reset light input is turned off, the output state is maintained.

Abstract: The present invention provides a set-reset flip-flop operating in an all-optical manner. In this invention, a set pulse is inputted from the setting port. In doing so, only oscillation in setting mode is generated at the multi-mode interference portion in waveguide. As a result, a non-inverting output Q is obtained from the non-inverting output port. This state is then continued even if the set pulse input goes off. Next, a reset pulse is inputted to the resetting port. In doing so, at the multi-mode interference portion, oscillation of light in the set mode is halted, and oscillation in the reset mode occurs. As a result, it is possible to obtain an inverting output Q-bar from the inverting output port. This state is then continued even if the reset pulse goes off.
