Squeezed states of light: generation and application

Harry J. Kimble

With the recent observations of squeezed states in several laboratories, attention now turns to improving the degree of achievable squeezing and to a number of exciting applications in optical physics. Our own research has concentrated on squeezed state production in three simple systems, each with a particular set of scientific and technological advantages and disadvantages.

Squeezed light generated by CPT-enabled phase sensitive amplification (Conference Presentation)

Fabien Bretenaker, Pascal Neveu, J. Delpy +4 more

The minimum resolvable signal in optical metrology and sensing applications is usually limited by the so-called standard quantum limit. One way to improve the signal-to-noise ratio is to use squeezed states of light. Squeezed light can be generated using different types of nonlinear interactions either in solid-state nonlinear crystals or in atomic systems. One way to generate squeezed light is to use a phase sensitive amplifier that will amplify one quadrature of the considered mode and deamplify the other one. We have recently shown that metastable helium vapor at room temperature can exhibit strong four-wave mixing effects and behave like a perfect phase sensitive amplifier when it is prepared in coherent population trapping situation. In this talk, we will present the application of this phase sensitive amplification to the generation of squeezed vacuum states of light and detail the performances and limitations of the systemThe minimum resolvable signal in optical metrology and sensing applications is usually limited by the so-called standard quantum limit.

Uses for squeezed coherent radiation

Bernard Yurke

Several laboratories have now successfully generated a new kind of light, squeezed light, which like laser light can be very intense. However, the quantum noise in one amplitude component of this light can be much less than the quantum noise of laser light.

Broadband squeezing via degenerate parametric amplification

David D. Crouch

We show that parametric amplification is capable of generating squeezed light over a wide band if materials with large ${\ensuremath{\chi}}^{(2)}$ nonlinearities can be found, and that the squeezing bandwidth can be enhanced considerably by phase matching away from degeneracy. We compare our results with similar results recently found for four-wave mixing in an optical fiber.
