Sources of Squeezed Light

based on continuous three wave mixing via degenerate optical paramteric amplification

In this lab we study some fundamental aspects of quantum optics. Squeezed light sources are the working horse for generating nonclassical states of light. Squeezed states of light have been studied well. Hence they can serve as a reference state for testing novel quantum state characterisation approaches. 

Two squeezers can be combined on a beam splitter to prepare the optical analog, so called two mode squeezed vacuum (TMSV), of the entangled state considered by Einstein, Podolski and Rosen in their seminal paper from 1935.
