项目摘要
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. ***For health, environmental and structural safety monitoring, different variables are often inter-related. For example, temperature is a parameter that impacts many others, and it is often impossible to use multiple sensors and their associated wires in the same location due to confined space. Using nonlinear fiber optics, we will also develop high-accuracy sensors, enabled by in-fiber structures with one sensing probe to realize measurements of two to three parameters at once. ******Another important application of nonlinear fiber optics is in the instrumentation of distributed fiber sensors based on nonlinear light scattering in optical fibers. These will allow temperature and strain (static) and acoustic waves (dynamic) to be detected over long distances and large areas. This will be the first time that static and dynamic monitoring will be achieved at the same time and in the same location. Optical fibers can "hear" underwater acoustic waves and identify abnormal sounds in gas, oil and water flow, resulting from pipeline cracks and deformation. By identifying the crack/deformation locations at earlier stages, we can reduce or prevent environmental contamination resulting from leakages in oil, gas or sewage water. Strain and temperature monitoring allows safety and security monitoring of highway bridges, dams, nuclear reactors, tunnels, high-speed railway tracks, critical areas, power generators and fiber communication links; all extremely relevant to Canada as natural resources represent our dominant economic activities. ******In proposed program, we design and develop sensor, laser and instruments, and then work with collaborators in industry and academia to modify the system towards applications. This gives our research the largest impact and provides HQP with an opportunity to build an international network of industrial and academic contacts, which make them well-positioned to make an impact in both industrial R&D and academic research. *** *** *****
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。* 对于健康、环境和结构安全监测,不同的变量往往是相互关联的。例如,温度是一个影响许多其他参数的参数,并且由于空间有限,通常不可能在同一位置使用多个传感器及其相关导线。利用非线性光纤,我们还将开发高精度传感器,通过光纤内结构,一个传感探头,实现一次测量两到三个参数。** 非线性光纤的另一个重要应用是基于光纤中非线性光散射的分布式光纤传感器的仪器。这将允许在长距离和大面积上检测温度和应变(静态)以及声波(动态)。这将是第一次在同一时间和同一地点实现静态和动态监测。光纤可以“听到”水下声波,并识别天然气,石油和水流中的异常声音,这些声音是由管道裂缝和变形引起的。通过在早期阶段识别裂缝/变形位置,我们可以减少或防止石油、天然气或污水泄漏造成的环境污染。应变和温度监测允许对公路桥梁、大坝、核反应堆、隧道、高速铁路轨道、关键区域、发电机和光纤通信链路进行安全和安保监测;所有这些都与加拿大非常相关,因为自然资源代表了我们的主要经济活动。** 在拟议的计划中,我们设计和开发传感器,激光器和仪器,然后与工业界和学术界的合作者合作,修改系统以实现应用。这使我们的研究产生了最大的影响,并为HQP提供了一个建立工业和学术联系的国际网络的机会,这使他们能够在工业研发和学术研究方面产生影响。
