Abstract

This paper presents a dual-side polished photonic crystal fiber (PCF)-based structure designed for refractive index (RI) sensing applications. The sensor leverages a gold layer deposited on the PCF surface to excite surface plasmons, enabling highly sensitive detection of changes in the surrounding refractive index. Numerical simulations, utilizing COMSOL software, were conducted to analyze the sensor's performance for pitch variation between 3.0 µm and 4.0 µm of the PCF structure. The analysis focuses on the mode characteristics and electric field distribution within the sensor. The simulation results demonstrate the influence of the PCF pitch on the sensor's optical properties, highlighting its potential for accurate RI detection in various applications.
