[1] McGill University, Montréal, QC, Canada

The Complementary Metal-Oxide-Semiconductor (CMOS) technology is a gateway to fabricating low cost electronic and photonic components to date. The Silicon-based nanophotonics platform leverages CMOS technology to fuel the effort to provide increasingly high-speed and high-bandwidth ... Read More

Numerical Analysis and Optimization of a Multi-Mode Interference Based Polarization Beam Splitter

Y. D'Mello [1], E. Elfiky [1], J. Skoric [1], D. Patel [1], D. Plant [1]
[1] McGill University, Montréal, QC, Canada

The progression toward smaller and faster photonic circuits has led to the development of nanophotonic platforms capable of compacting many devices onto an integrated chip. These devices, as well as the input and output grating couplers, are sometimes polarization dependent, which allows ... Read More

COMSOL Multiphysics® Implementation of a Genetic Algorithm Routine for Optimization of Flat Optics

Cancer is one of the leading causes of deaths worldwide. According to the American Cancer Society, there will be about 700,000 cancer related deaths in US in 2017. Cancer mortality will be reduced if it is detected and treated at the early stages. Previous studies have shown that ... Read More

Simulating Surface Plasmons at Metal Surfaces and Its Application in Optoelectronic Devices

L. Wang [1],
[1] Konica Minolta Laboratory, San Mateo, CA, USA

Surface plasmon polaritons (SPP) are guided electromagnetic modes of a metal/dielectric interface. These surface electromagnetic waves arise through the coupling of the incident electromagnetic radiation with the collective charge-density oscillations of the free electrons in a metal. ... Read More
