All-optical logic gate device based on resonant ring-MIM waveguide coherent regulation and control

Abstract

The invention discloses an all-optical logic gate device based on resonant ring-MIM waveguide coherent regulation and control. The all-optical logic gate device comprises a silicon dioxide substrate plated with an Ag film, a resonant ring-MIM waveguide combined structure arranged on the substrate and formed by air slits, and at least two ports arranged on an MIM waveguide. Symmetric incident conditions are introduced into a single-side or double-side port, and a reasonable output end is arranged; all-optical coherence regulation and control can be realized on the resonant ring-MIM waveguide byadjusting the phase difference of incident light so as to design different logic gate functions including an AND gate, an OR gate, a NOT gate and an XOR gate, and simple switching between different logic gates under the same structure can be completed. The device has potential application prospects in the fields of optical signal processing technologies, ultra-compact photonic integrated devices,sensing technologies and the like.
