Abstract

We perform coherent constellation diagram measurements of phase modulated data before and after a saturated parametric amplifier, and find a novel kind of pump-induced phase noise in the amplifier.

Noise performance of parametric amplifiers is typically calculated assuming un-depleted operation. However, in many applications especially when applied as regenerative amplifiers in systems based on phase shift keyed modulation schemes, this assumption is not valid. Here we show the impact on accumulated spontaneous emission for a parametric amplifier operated in saturation.

We experimentally investigate the phase and amplitude transfer functions of a non-degenerate idler PSA in saturation. A regime in which phase noise can be reduced with very low amplitude penalty is identified.

Noise properties of phase-(in)sensitive parametric amplifiers

Colin J. McKinstrie, Z. Tong

One- and two-mode phase-sensitive parametric amplifiers, based on the inverse and direct modulation instability, respectively, were demonstrated recently. The quantum noise properties of these devices will be described in detail, and the consequences of these properties for phase-sensitive communication links will be discussed.
