Loss-insensitive quantum noise reduction in a Raman amplifier with coherent feedback
Jianmin Wang, Rong Zhu, Z. Y. Ou
A quantum amplifier usually adds extra noise inevitably through coupling to internal degrees of freedom while amplifying the signal. The introduction of quantum correlations can ef…

Frequency-shifted laser feedback interferometry in non-planar ring oscillators
Rong Zhu, Xuezhen Gong, Wenxun Li +7
Laser feedback interferometry (LFI) has a wide range of applications such as displacement, distance and velocity measurements. LFI has been realized in many types of lasers but has…
