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…
