Fiber-optics linear passive logic gates for all-optical computing******

能够在恶劣环境中执行计算任务的强大、节能的数据处理系统对于安全、国防和空间应用至关重要。光子技术由于其固有的抗电磁干扰能力、处理高速数据信号的适用性以及与光纤传输系统的兼容性，是此类应用的优秀候选者。最新的技术将使有关数据信号从发送方传送到接收方时能够进行信息处理操作。迄今为止，已经提出了许多光纤数据处理系统的解决方案，特别是光子逻辑门。然而，这些依赖于数据信号和传输介质之间的非线性相互作用，通常导致高功率预算要求和低信噪比，这两个问题在上述应用领域都是有害的，特别是在恶劣环境中运行。****该项目旨在解决当前光逻辑门处理器的上述关键限制。为了实现这一目标，INRS的研究人员将与Optii公司（一家100%的加拿大高科技初创公司）合作，共同开发和实现零开关能量全光无源逻辑门，这是INRS团队首席研究员最近展示的一个突破性概念。这一新概念将首次以全光纤格式实现，为实际恶劣环境下的超高速数据信号处理提供坚实的平台，具有出色的能效和鲁棒性。****由此产生的专业知识和高素质人才的培训将使加拿大在节能宽带数据处理技术和系统方面处于领先地位。******

Robust, energy-efficient data processing systems capable of carrying out computational tasks in harsh environments are essential for security, defense, and space applications. Photonic technologies are excellent candidates for such applications, due to their inherent immunity to electromagnetic interference, their suitability to process high-speed data signals and their compatibility with fiber-optics transmission systems. The latest would enable information-processing operations to be carried out as the data signal of interest is transferred from sender to receiver. A number of solutions for fiber-optics data processing systems, particularly photonic logic gates, have been proposed to date. However, these rely on nonlinear interaction between the data signal and the transmission medium, typically resulting in high power-budget requirements and low signal-to-noise ratios, both detrimental issues in the mentioned application fields, particularly for operation in harsh environments. ****This project is aimed at solving the mentioned critical limitations of current optical logic gate processors. Towards this goal, researchers from INRS will work with Optii Corp, a 100% Canadian hi-tech start-up company, towards the development and practical realization of zero-switching-energy all-optical passive logic gates, a ground-breaking concept recently demonstrated by the INRS team's lead investigator. This new concept will be implemented for the first time in an all-fiber-optics format, providing a solid platform for ultra-high-speed data signal processing in practical harsh environments, with excellent energy efficiency and robustness. ****The generated know-how and the training of highly-qualified personnel will place Canada in a leading position in energy-efficient broadband data processing technologies and systems.******
