  • EIT-based photonic logic gate
    Patent number: 8675268
    Abstract: An electromagnetically induced transparent (EIT)-based photonic logic gate. The electromagnetically induced transparent (EIT)-based photonic logic gate is a photonic crystal (PC) and electromagnetically induced transparent (EIT)-based stacked layer which is constituted by a photonic crystal (PCs) layers and an electromagnetically induced transparent material layers. For the photonic crystal (PCs) and electromagnetically induced transparent (EIT)-based stacked layer, a probe field is an input signal which is emitted from the photonic crystal layer and a control field is a control signal which is emitted from the electromagnetically induced transparent material layers. The probe field is an input signal which is emitted from the electromagnetically induced transparent material layers. By varying the detune frequency of probe field and Rabi frequency of control field, the band gap structure can be adjusted.

  • EIT-BASED PHOTONIC LOGIC GATE
    Publication number: 20130016411
    Abstract: The present invention provides an EIT-based photonic logic gate, which is constituted by EIT-based stack layers of periodic array of photonic crystal (PCs) layers and EIT (Electromagnetic Induced Transparent) material layers. The input probe signals are incident on the first photonic crystal layer, passing through one or more than one PCs-EIT interfaces and transmitted out from the last EIT material layer. Control filed as the enable signals are incident on each EIT layer to activate the optical logic gate. By varying the detune frequency of probe field and Rabi frequency of control field, its band gap structure can be adjusted. Henceforth, the tunable optical EIT-based photonic logic gate can be achieved as user required.
