Abstract

In modern time, PCF based sensors are primarily attribute towards strong light–matter interaction, superior sensitivity, and versatile structural design providing for advanced optical sensing application which collectively enables efficiency and precise sensing. This paper presents a thorough review of photonic crystal fiber (PCF)–based sensing technologies, emphasizing their operating principles, performance metrics, and diverse application domains. It includes an in-depth comparative analysis of PCF sensors used in chemical, biomedical, liquid analyte, biosensing, environmental, and refractive index sensing applications. The sensing efficiency of PCF-based devices depends on numerous factors such as fiber geometry, host material, operating wavelength, light-guiding mechanism, refractive index of the target analyte, air-hole dimensions and distribution, lattice pitch, birefringence, confinement loss, fabrication accuracy, metal or dielectric coatings, surface functionalization, as well as external environmental conditions including temperature and pressure. A wide range of PCF structural designs namely hexagonal, square, circular, triangular, hollow-core, solid-core, rectangular porous, decagonal, elliptical, and asymmetric structures are discussed, with their corresponding sensing mechanisms and design strategies systematically examined. A tabulated comparison of representative PCF sensors is presented, followed by a discussion of current challenges, fabrication limitations.
