Research Summary
Polymer-based photonic-crystal pressure sensing
The study investigates a pressure sensor based on a polymer photonic-crystal slab. Pressure-dependent changes in the sensing structure and refractive index are evaluated through shifts in resonance wavelength.
The photonic structure is numerically optimized by varying geometric parameters and evaluating the resulting optical response. The optimized device is then studied across different applied pressures to characterize its sensing performance.
The optical analysis combines finite-difference time-domain simulation with plane wave expansion methods for resonance and photonic-band-structure evaluation.
