Tunable Twin Beam Generation by Beam Coupling in Photorefractive Media
Twin beams that exhibit intensity correlations below the shot noise limit have been generated using several different methods. These include optical parametric oscillation1 and amplification2, and four-wave mixing3. Although methods of producing twin beams, and beams with quadrature squeezing, are now well established the necessary technology is often very complex. See, for example, the system put together by Kimble and collaborators for the generation of tunable squeezed light4. The analysis presented here is motivated in part by the quest for simpler methods.
