Theoretical study of the quantum noise in phase-sensitive heterodyne detection with a bichromatic local oscillator
Sheng Feng, Dechao He, Heng Fan
A traditional heterodyne detector, as a phase-insensitive device, suffers the well-known 3 dB noise penalty caused by image sideband vacuum. In contrast, a heterodyne detector with…
Experimental study of a phase-sensitive heterodyne detector
Heng Fan, Dechao He, Sheng Feng
It is believed that the quantum behaviors of homodyne detectors and traditional heterodyne detectors can be fully understood in the context of the quantum theory of optical detecti…
Experimental Study of Quantum Noise in Optical Heterodyne Detection
Dechao He, Boya Xie, Yu Xiao +1
We experimentally investigate the quantum-noise performance of a conventional heterodyne detector and find significant discrepancy between experiment and theory. Further investigat…
Quantum Noise in Conventional Optical Heterodyne Devices
Dechao He, Boya Xie, Yu Xiao +1
By invoking the quantum theory of optical coherence, we theoretically show that the quantum noise in conventional optical heterodyne devices, which were previously identified as us…
