Overview

Proposed optical NOR gate achieves 7.72 dB contrast ratio in photonic circuits, highlighting potential for integration.

Key Points

  • The proposed optical NOR gate achieves a minimum contrast ratio of 7.72 dB, indicating effective logic performance.
  • Key metrics include a response time of 0.273 ps and a calculated bit rate of approximately 797.4 GHz with photonic integration.
  • Simulation employed combines Plane Wave Expansion Method and Finite-Difference Time-Domain method for accuracy.
  • Simple structure of 9.135 μm x 9.135 μm may enable future developments in optical circuits.
