New-age smart technologies necessitates the deployment of large number of sensors connected via Internet of things (IoT). Seamless deployment of IoT demands communication devices that can support large data loads at high speed. Thus, efficient photonic sensors and detectors with large and tunable bandwidths are required to meet the market demands for Canada's Smart transformation. Here, we propose to develop novel two dimensional (2D)- transition metal dichalcogenides (TMD) based photonic devices and sensors exploiting the unique carrier transport properties of this class of materials. 2D-TMD materials show excellent optoelectronic properties that will be utilized for the development of high-performance photonic detectors using a resonance-based approach.To develop the proposed photonic detectors, the University of Calgary team will collaborate with the "nanomaterial growth and nanofabrication laboratory" from the Stevens Institute of Technology. The US collaborators have great expertise in the development of emerging 2D materials, including 2D-TMDs, that will contribute significantly to the fabrication of our envisioned photonic devices. The UofC team has expertise in electronic characterization of such exotic 2D materials. The project will synergize the expertise of the teams and make a roadmap for Canada to participate in the global photonics market that can have broad collaborative and technology translational opportunities.This collaboration will foster diverse HQP training with equity, diversity, and inclusion frameworks in mind. By exploring this new class of materials, potential new technologies that can garner a transformative opportunity to make Canada a part of the cutting-edge global photonics industry. This technology can also extend to other manufacturing processes and possibly enable new commercialization opportunities such as in 'imaging-sensors'. The research will benefit Canada by the training of new HQPs with a variety of professional and technical skills.

新时代的智能技术需要部署大量通过物联网（IoT）连接的传感器。物联网的无缝部署需要能够高速支持大数据负载的通信设备。因此，高效的光子传感器和探测器，大和可调带宽需要满足加拿大的智能转型的市场需求。在这里，我们建议开发新的二维（2D）-过渡金属二硫属化物（TMD）的光子器件和传感器，利用这类材料的独特的载流子输运特性。2D-TMD材料显示出优异的光电性能，将用于使用基于共振的方法开发高性能光子探测器。为了开发拟议的光子探测器，卡尔加里大学团队将与史蒂文斯理工学院的“纳米材料生长和纳米纤维实验室”合作。美国合作者在新兴2D材料（包括2D-TMD）的开发方面拥有丰富的专业知识，这将为我们设想的光子器件的制造做出重大贡献。UofC团队在这种奇异的2D材料的电子表征方面具有专业知识。该项目将协同团队的专业知识，并为加拿大参与全球光子市场制定路线图，可以获得广泛的合作和技术转化机会。这种合作将促进多元化的HQP培训，并考虑到公平，多样性和包容性框架。通过探索这类新材料，潜在的新技术可以获得一个变革性的机会，使加拿大成为全球尖端光子产业的一部分。该技术还可以扩展到其他制造工艺，并可能实现新的商业化机会，例如“成像传感器”。这项研究将通过培训具有各种专业和技术技能的新的HQP使加拿大受益。
