In the past years, my research on chalcogenide glass has focused on exploiting nonlinearity and engineer chromatic dispersion to develop the functionality of chalcogenide microwires exclusively at a wavelength of 1.5 micron. The research objective in the current application is to take advantage of the high-nonlinearity and transparency of chalcogenide glass in the wavelength range of 1.5-10.0 microns to develop broadband sources in the mid-IR. For this purpose, two thrust are being proposed: 1) the fabrication of microwire-based components, 2) the fabrication of chalcogenide waveguides and microresonators. The proposed project addresses a growing concern across Canada: developing sensing tools for the industry and improving the quality and affordability of health services. Photonics technologies in the mid-infrared are lagging behind near-infrared photonics (800-1700 nm) which benefited from exceptional market competition and activity in the telecommunication market. As a result, few sources are available in the wavelength range of 1700 nm and beyond. This project harnesses current photonics technology and a scientifically mature optical material, namely chalcogenide glass, to close important wavelength gaps in the market offerings. Highly qualified personnel will emerge from this project. The graduate students will be specialists in photonics and mid-IR technologies, two topics of great importance and holding many challenges for years to come. Every year, 2 PhD candidates, 1MEng candidate and 1 undergraduate student will be simultaneously involved in this project.

在过去的几年中，我对硫族化物玻璃的研究重点是利用非线性和工程色散来开发硫族化物微线仅在 1.5 微米波长下的功能。目前应用的研究目标是利用硫系玻璃在1.5-10.0微米波长范围内的高非线性和透明性来开发中红外宽带光源。为此，提出了两个重点：1）基于微线的组件的制造，2）硫族化物波导和微谐振器的制造。 拟议的项目解决了加拿大各地日益关注的问题：为该行业开发传感工具并提高医疗服务的质量和可负担性。中红外光子技术落后于近红外光子技术（800-1700 nm），后者受益于电信市场的异常市场竞争和活动。 因此，1700 nm 及以上波长范围内可用的光源很少。该项目利用当前的光子技术和科学成熟的光学材料（即硫系玻璃）来缩小市场产品中的重要波长差距。 该项目将培养高素质人才。研究生将成为光子学和中红外技术方面的专家，这两个主题非常重要，并且在未来几年将面临许多挑战。每年有2名博士生、1名硕士生和1名本科生同时参与该项目。
