Design and fabrication of nano-photonics-based all-optical flip-flop switch

Abstract

A photonic crystal- and quantum dot-based all-optical flip-flop switch (PC-FF) capable of synchronizing with high frequency clock was fabricated for a future optical digital signal processing device with high-speed capability of 40 Gb/s and beyond. Nanostructures constructing the PC-FF exhibit excellent characteristics and suggest successful optical FF demonstration.
