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. Henceforth, the tunable optical electromagnetically induced transparent (EIT)-based photonic logic gate can be achieved.
