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.******

能够在恶劣环境中执行计算任务的健壮、高能效的数据处理系统对于安全、国防和空间应用至关重要。光子技术因其固有的对电磁干扰的免疫力、适合处理高速数据信号以及与光纤传输系统的兼容性而成为此类应用的极佳候选者。最新的将使信息处理操作能够在感兴趣的数据信号从发送者传输到接收者时执行。到目前为止，已经提出了许多用于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，特别是对于在恶劣环境中的操作。*本项目旨在解决上述当前光逻辑门处理器的关键局限性。为了实现这一目标，INRS的研究人员将与加拿大100%高科技初创公司Optii Corp合作，开发并实际实现零开关能量全光无源逻辑门，INRS团队的首席研究员最近展示了这一突破性的概念。这一新概念将首次以全光纤格式实施，为实际恶劣环境中的超高速数据信号处理提供坚实的平台，具有出色的能效和稳健性。*产生的技术诀窍和高素质人员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。*
