Spectrum of squeezing and photocurrent shot noise: a normally ordered treatment
Abstract
In the present treatment of squeezed optical field detection for cases generated by intracavity nonlinear-optical interactions, attention is given to the relationship between the cavity mode quantum-statistical properties and those of the field at a detector that is placed outside the cavity. The photocurrent spectrum in optical homodyne detection is determined, and the squeezing spectrum is defined. Shot noise is found to naturally arise from the self-correlation of photocurrent pulses. The spectrum derived is converted into nonnormally ordered, nontime-ordered form in order to recover the results of the earlier treatments and their interpretation of shot noise in terms of local-oscillator quantum noise, signal quantum noise, and detector efficiency quantum noise.
