Enhanced sensitivity of low-frequency signal by using broad squeezed light and bichromatic local oscillator
Wei Li, Yuanbin Jin, Xudong Yu +1
We experimentally study a protocol of using the broadband high frequency squeezed vacuum to detect the low-frequency signal. In this scheme, the lower sideband field of the squeeze…
Measurement of the squeezed vacuum state by a bichromatic local oscillator
Wei Li, Xudong Yu, Jing Zhang
We present the experimental measurement of a squeezed vacuum state by means of a bichromatic local oscillator (BLO). A pair of local oscillators at 5 MHz around the central fr…
Experimental study of balanced optical homodyne and heterodyne detection by controlling sideband modulation
Wei Li, Zengming Meng, Xudong Yu +1
We experimentally study optical homodyne and heterodyne detections with a same setup, which is flexible to manipulate the signal sideband modulation. When the modulation only gener…
Triply-resonant Optical Parametric Oscillator by Four-wave Mixing with Rubidium Vapor inside an Optical Cavity
Xudong Yu, Min Xiao, Jing Zhang
We present an experimental demonstration of simultaneous above-threshold oscillations of the Stokes and anti-Stokes fields together with the single pumping beam with rubidium atoms…
Multi-normal-mode splitting of a cavity in the presence of atoms -- towards the superstrong coupling regime
Xudong Yu, Dezhi Xiong, Haixia Chen +3
Multi-normal-mode splitting peaks are experimentally observed in a system with Doppler-broadened two-level atoms inside a relatively long optical cavity. In this system, the atoms-…
