TM Beam Propagation in Photonic Integrated Circuits -Done

Project supervisor: Yoav Hazan

Optical detection of ultrasound is mostly done with high-Q factor optical resonators. These optical resonators can be manufactured in Silicon wafers, where the resonators spectra are highly sensitive to the polarization state of the propagating beam. TM polarized beam can potentially increase manufacturing yield as well as sensing sensitivity by an order of magnitude.

Project Status: Available

Y. Painchaud, et al.,2012

Project requirements:

  1. Simulations comparing TE and TM beam propagations through phase-shifted Bragg grating resonators in Silicon waveguide.
  2. Optimization of waveguide dimensions for narrow resonance and high transmission efficiency.

Advancement options:

  1. Simulations of different resonator structures, and the sensitivity for the two difference polarization states.
