Abstract

We propose an optical flip-flop circuit composed of two-port resonant-tunneling filters based on a two-dimensional photonic crystal slab with a triangular air-hole lattice. This circuit can function as an optical digital circuit that synchronizes input data with a clock. In this report, we demonstrate that this circuit can achieve a fast operating speed with a response time of about 10 ps and a low operating power of 60 mW by employing a two-dimensional FDTD calculation.
