In this video, we explain the fundamental working principle of a Photonic Crystal Fiber (PCF) based Surface Plasmon Resonance (SPR) sensor in a clear and intuitive way. This video is designed for beginners, researchers, and graduate students who are starting research on PCF-SPR sensors for refractive index sensing, biosensing, and chemical sensing applications.
Paper DOI: https://doi.org/10.1039/D4NA00812J
We discuss:
What Photonic Crystal Fiber (PCF) is
What Surface Plasmon Resonance (SPR) means
How SPR is excited at the metal–dielectric interface
How PCF guides light and couples energy to surface plasmons
Why resonance loss peak shifts with refractive index change
The physical meaning of confinement loss in PCF-SPR sensors
This video builds the theoretical foundation required before moving to COMSOL Multiphysics simulation, geometry design, material selection, and performance analysis.
