The use of mid infrared lasers or THz sources is increasing markedly across a variety of disciplines, including astronomy, medicine, and sensing and security. However, there are limited sources of mid-infrared lasers available. In order to develop mid infrared laser and THz sources, quantum cascade lasers have been intensively researched for a decade; however, cryogenic operating temperatures are required, which limits their application severely. Alternatively, using non-silica high nonlinear media to generate mid infrared light and supercontinuum has been considered a reliable and feasible technology. Globally, significant progress has been made in developing speciality fibers and waveguides for use in mid infrared laser sources. For example, CorActive and INO in Quebec have developed highly nonlinear chalcogenide fibers for mid infrared applications. In addition to quantum cascade lasers, there are typically two methods for developing mid-infrared lasers. One method is to generate mid infrared narrow band light beam based on cascaded stimulated Raman effect using the specialty fibers and fiber-based mode-locked lasers. The second method to achieve mid infrared lasers is to use supercontinuum generated by using specialty fibers and fiber-based mode locked lasers. In this project, we will investigate generation of mid infrared supercontinuum using specialty fibers and InP quantum dot mode locked lasers. If successful, this project will yield a low-cost and compact mid-infrared laser source. The final outcome of this project is expected to be a supercontinuum spanning from 1600 nm to 4000 nm with high output power.

中红外激光器或太赫兹源的使用在各种学科中显着增加，包括天文学，医学，传感和安全。 然而，可用的中红外激光源有限。为了发展中红外激光和太赫兹光源，近十年来人们对量子级联激光器进行了深入的研究，但是量子级联激光器的工作温度要求很低，这严重限制了量子级联激光器的应用。另外，利用非硅高非线性介质产生中红外光和超连续谱被认为是一种可靠可行的技术。 在全球范围内，在开发用于中红外激光源的特种光纤和波导方面取得了重大进展。例如，魁北克的CorActive和INO已经开发出用于中红外应用的高度非线性硫族化物光纤。 除了量子级联激光器之外，通常还有两种方法用于开发中红外激光器。一种方法是利用特殊光纤和光纤锁模激光器级联受激拉曼效应产生中红外窄带光束。实现中红外激光器的第二种方法是使用通过使用特殊光纤和基于光纤的锁模激光器产生的超连续谱。 在这个项目中，我们将研究使用特殊光纤和InP量子点锁模激光器产生中红外超连续谱。 如果成功，该项目将产生低成本和紧凑的中红外激光源。 该项目的最终成果预计将是一个从1600 nm到4000 nm的超连续谱，具有高输出功率。
