Quantum-Enhanced Polarimetric Imaging
Meng-Yu Xie, Su-Jian Niu, Zhao-Qi-Zhi Han +8
Polarimetric imaging, a technique that captures the invisible polarization-related properties of given materials, has broad applications from fundamental physics to advanced fields…
Effective multiband synthetic four-wave mixing by cascading quadratic processes
Li Chen, Zheng Ge, Su-Jian Niu +9
Four wave mixing (FWM) is an important way to generate supercontinuum and frequency combs in the mid-infrared band. Here, we obtain simultaneous synthetic FWM in the visible and mi…
Quantum entanglement enabled ellipsometer for phase retardance measurement
Meng-Yu Xie, Su-Jian Niu, Yin-Hai Li +6
An ellipsometer is a vital precision tool used for measuring optical parameters with wide applications in many fields, including accurate measurements in film thickness, optical co…
Mid-Infrared Upconversion Imaging Under Different Illumination Conditions
Zheng Ge, Zhao-Qi-Zhi Han, Yi-Yang Liu +9
Converting the medium infrared field to the visible band is an effective image detection method. We propose a comprehensive theory of image up-conversion under continuous optical p…
Thermal camera based on frequency upconversion and its noise-equivalent temperature difference characterization
Zheng Ge, Zhi-Yuan Zhou, Jing-Xin Ceng +5
We present a scheme for estimating the noise-equivalent temperature difference (NETD) of frequency upconversion detectors (UCDs) that detect mid-infrared (MIR) light. In particular…
Harmonics-assisted optical phase amplifier
Wu-Zhen Li, Chen Yang, Zhi-Yuan Zhou +7
The change in the relative phase between two light fields serves as a basic principle for the measurement of the physical quantity that guides this change. It would therefore be hi…
Up-conversion detection of mid-infrared light carrying orbital angular momentum
Zheng Ge, Chen Yang, Yin-hai Li +5
Frequency up-conversion is an effective method of mid-infrared (MIR) detection by converting the long-wavelength photons to the visible domain, where efficient detectors are readil…
Measuring the tuning curve of spontaneous parameter down-conversion using a comet-tail-like pattern
Chen Yang, Zhi-Yuan Zhou, Yan Li +5
The comet-tail-like interference patterns are observed using photons from the spontaneous parametric down-conversion (SPDC) process. The patterns are caused by the angular-spectrum…
