Research Experience

Research development

Thesis-to-Publication Development

Polymer-Based Photonic Crystal Pressure Sensor

  • Developed the M.Sc. research into a journal manuscript by adapting the pressure-sensor model to a polymer-based photonic-crystal slab and revising the material assumptions for the publication-stage study.
  • Presented systematic cavity-radius sweeps and analyzed resonance shifts, quality factor, transmission, and pressure sensitivity using PWE/FDTD-based simulations.
  • Revised methodology, technical explanations, figures, literature comparison, and discussion in response to multi-reviewer feedback.
  • Published the revised work as sole author in Optical and Quantum Electronics in 2024.

Master's Thesis Research

Coupled-Cavity Photonic Waveguide Pressure Sensor

  • Modeled and systematically modified a coupled-cavity photonic-crystal waveguide pressure-sensor architecture using RSoft, plane-wave expansion (PWE), and finite-difference time-domain (FDTD) methods.
  • Investigated cavity geometry, coupling, resonance behavior, and pressure-dependent optical response through systematic radius variation.
