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.

在过去的几年里，我对硫系玻璃的研究主要集中在利用非线性和工程色散来开发硫系微线在1.5微米波长下的功能。本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，开发中红外宽带光源。为此，提出了两种推力：1)制造基于微线的元件，2)制造硫化物波导和微谐振器。
