Designing and prototyping capability to develop new devices for low power, low cost and small footprint

With the Canadian capability in silicon Photonics, III-V semiconductors, and photonic integrated circuits we could develop strong advanced laser and sensor technologies.

Our anchor presentation is “Hybridization in Plasmonic Devices: a path to outperform their Si Counterparts ” by Amr S. Helmy | Professor at the University of Toronto and deals with integrated optical devices and resonators, realistic utilization of the superior wave-matter interaction offered by plasmonics is typically impeded by Ohmic loss, which increase rapidly with mode volume reduction. Although coupled-mode plasmonic structures have demonstrated effective alleviation of the loss-confinement trade-off, stringent symmetry requirements must be enforced for such reduction to prevail. In this work, we report an asymmetric plasmonic waveguide that is not only capable of guiding subwavelength optical mode with long-range propagation but is also unrestricted by structural, material, or modal symmetry. In these composite hybrid plasmonic waveguides (CHPWs), the versatility afforded by the coupling dissimilar plasmonic modes allow better fabrication tolerance and provide more degrees of design freedom to simultaneously optimize various device attributes. Specifically, experimental realization of CHPW demonstrates propagation loss and mode area of only 0.03 dB/μm and 0.002 μm2 respectively, corresponding to the smallest combination amongst long-range plasmonic structures reported to-date. As these waveguide attributes are robust over large process conditions and optical bandwidth, CHPW ring resonator with 2.5 μm radius has been realized with record Purcell factor compared to existing plasmonic and dielectric resonators of similar radii.

Each participant can choose to make a 5 min presentation on the topic or say a couple of words about their capabilities and interest in the topic.
