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.******
