Abstract :
An all-optical delay flip flop is designed and described using two quantum dot semiconductor assisted Mach-Zehnder interferometers in this study. The flip flop has one enable input that allows for both positive and negative edge triggered operation without changing the design of the circuit. It is reconfigurable by design. Numerical simulations have been conducted to assess the performance of the circuit.
