Electromagnetically induced grating: Homogeneously broadened medium
A strong coupling standing wave, interacting with three-level L-type ~or ladder-type! atoms, can diffract a weak probe field ~propagating along a direction normal to the standing wave! into high-order diffractions, a phenomenon which we name electromagnetically induced grating ~EIG!. We develop in this work a theory for studying EIG in a homogeneously broadened medium consisting of three-level ...
متن کاملNarrow-Band Biphoton Generation near Atomic Resonance
Generating nonclassical light offers a benchmark tool for the fundamental research and potential applications in quantum optics. Conventionally, it has become a standard technique to produce the nonclassical light through the nonlinear optical processes occurring in nonlinear crystals. In this review we describe using cold atomic-gas media to generate such nonclassical light, especially focusin...
متن کاملBright narrowband biphoton generation from a hot rubidium atomic vapor cell
We demonstrate the generation of high-quality narrowband biphotons from a Doppler-broadened hot rubidium atomic vapor cell. Choosing a double-K atomic energy level scheme for optimizing both spontaneous four-wave mixing nonlinear parametric interaction and electromagnetically induced transparency (EIT), we achieve a biphoton spectral brightness as high as 14 000 s MHz . Meanwhile, we apply a sp...
متن کاملFAST TRACK COMMUNICATION An electromagnetically induced grating by microwave modulation
We study the phenomenon of an electromagnetically induced phase grating in a double-dark state system of 87Rb atoms, the two closely placed lower fold levels of which are coupled by a weak microwave field. Owing to the existence of the weak microwave field, the efficiency of the phase grating is strikingly improved, and an efficiency of approximately 33% can be achieved. Under the action of the...
