Plasmonic spectral filters from the visible to the far-infrared region

点击翻译按钮获取中文摘要

Optical spectral filtering is a crucial aspect of applications that involves light. The areas where spectral filtering is utilized are vast and diverse: among the fields where optical filtering is of need are medical diagnostics, communication networks, photography, spectroscopy, food-quality control, gas, chemical and biological sensors, and many others. Iridian Spectral Technologies Ltd (Iridian) is an Ottawa-based diversified supplier of thin film technology covering many application areas and operating in a global market. The company invests heavily in research and development in order to remain competitive and to keep its position at the forefront of optical filtering technology. Implementing new approaches in creating optical filters at lower cost, with better performance, as well as expanding the company's products to new wavelength ranges is key to successful competition in the market place. This Strategic collaboration aspires to improve the company's existing filtering technology especially in the mid-infrared wavelength range. The approach we seek to implement relies on metamaterials, that is, artificial 2D and 3D structures produced by micro and nanofabrication. If successful, this could become a new approach that could potentially lead to breakthroughs in filter technology, making this Canada-based enterprise a pioneer in the field and strengthening its position in global market. This project will also provide training to highly qualified and skilled personnel, benefiting from an environment enriched by an industrial dimension and promoting effective knowledge transfer to industry.
