PROJECT 01

Optimized Integration of Quantum Emitters in Silicon Platforms

Numerical investigation of coupling between quantum emitters and integrated optical waveguides in silicon-based photonic platforms.

Conceptual visualization of a quantum emitter coupled to an integrated optical waveguideProject architecture reference supplied by the researcher. It illustrates the broader device concept; it is not presented as an output of my COMSOL simulations.

Research context

This project explored the coupling of quantum emitters to integrated optical waveguides. The illustration represents an emitter near a waveguide and the guided optical mode; it is a conceptual visualization, not a COMSOL result.

My contribution

I used COMSOL Multiphysics to simulate coupling between quantum emitters and optical waveguides. The specific parameter studies, model geometry, and quantitative results will be documented when available.
