Abstract

I will review the physics of parametric amplification and frequency conversion, and describe three recent applications of parametric devices: (a) low-noise four-fold multicasting, (b) hybrid amplification and (c) quantum-state-preserving frequency conversion for quantum communication systems.

Quantum noise in optical parametric amplification: a means to achieve noiseless optical functions

We describe some limitations of the noise performance of classical optical devices which are directly related to the Poissonian statistics associated with ordinary laser beams. We show that quantum optics, via optical parametric amplification, allows us to circumvent these limitations in order to realize certain noiseless optical functions such as amplification, duplication, detection and distribution of optical signals.

Nonlinear Optical Frequency Conversion

M. M. Fejer

The colored rings shown in figure 1 are a spectacular manifestation of one type of nonlinear optical frequency conversion: parametric amplification of quantum noise. The amplification in this case is produced by the propagation of an intense pulse of ultraviolet radiation through a crystal of barium borate. When intense electromagnetic radiation propagates through such a material, whose polarization response at optical frequencies manifests a strongly nonlinear dependence on electric field amplitude, nonlinear mixing of the input radiation generates new spectral components. We can exploit this phenomenon to generate coherent radiation at frequencies for which we have no convenient laser sources.
