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

光谱滤波是涉及光的应用的一个关键方面。利用光谱滤波的领域广泛而多样：需要光学滤波的领域包括医疗诊断、通信网络、摄影、光谱学、食品质量控制、气体、化学和生物传感器以及许多其他领域。Iridian光谱技术有限公司（Iridian）是一家位于渥太华的薄膜技术多元化供应商，覆盖多个应用领域，并在全球市场开展业务。公司大力投资于研究和开发，以保持竞争力，并保持其在光学滤波技术的前沿地位。采用新方法以更低的成本制造光学滤波器，具有更好的性能，以及将公司的产品扩展到新的波长范围是在市场竞争中取得成功的关键。**此次战略合作旨在改进公司现有的过滤技术，特别是在中红外波长范围内。我们寻求实现的方法依赖于超材料，即由微纳米制造产生的人工2D和3D结构。如果成功，这可能成为一种新的方法，可能会导致过滤器技术的突破，使这家加拿大企业成为该领域的先驱，并加强其在全球市场的地位。该项目还将向高素质和有技能的人员提供培训，使他们受益于工业层面丰富的环境，并促进向工业的有效知识转移。******

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.******
