My research focuses on fiber optics technology. We achieve enhanced nonlinear effects in fibers by making structures in the fibers. Then, based on time and frequency features of four wave mixing and stimulated scattering; we develop novel fiber-based devices such as ultra-narrow linewidth filters, low-noise lasers, optical random number generators and entangled fiber laser sources. They offer high precision, compact and cost-effective solutions for metrology, sensors and fiber communications. In quantum communications, a single photon source and detector are often used; therefore, the communication signal is limited by the frequency and phase noise of the optical signal. It is very important to develop a narrow linewidth optical filter (kHz range) and a laser source with ultra-low phase and frequency noise (unavailable commercially) to ensure long-distance quantum communication. The optical entangled source is the key for secure communications.

我的研究重点是光纤技术。我们通过在光纤中制作结构来增强光纤的非线性效应。然后，基于四波混频和受激散射的时频特性，我们开发了新型的基于光纤的器件，如超窄线宽滤波器、低噪声激光器、光学随机数发生器和纠缠光纤激光源。它们为计量、传感器和光纤通信提供高精度、紧凑且经济高效的解决方案。在量子通信中，通常使用单个光子源和探测器;因此，通信信号受到光信号的频率和相位噪声的限制。研制窄线宽（kHz范围）的光学滤波器和具有超低相位和频率噪声（商业上不可用）的激光源，以确保长距离量子通信是非常重要的。光纠缠源是实现保密通信的关键。
