Оптичні датчики на фотонно-кристалічному волокні

Abstract

Photonic crystal fiber (PCF) structure containing a solid core and periodic air-hole cladding for optical sensing is considered. Python packages (matplotlib, numpy) are used for modeling the structure and investigation of spectral characteristics of the photonic crystal fiber system. Resonances in spectral characteristics that appear when the refractive index of the analyte changes are considered. High sensitivity of the system to external parameters (refractive index, temperature, pressure) inherent in the photonic crystal fiber sensor is studied for different values of the system parameters
