Design and characterization of an ultra-sensitive photonic crystal fiber-based sensor for precise detection of alcohols in the THz regime

Abstract

In an era where the precise detection of alcohols is increasingly vital across a broad spectrum of industries, from healthcare to petrochemicals, the introduction of an innovative, highly sensitive photonic crystal fiber-based sensor represents a significant advancement. This pioneering research unveils a sensor engineered explicitly for the accurate detection of ethanol, methanol, and propanol, operating within the terahertz (THz) frequency range. Utilizing the exceptional attributes of photonic crystals and incorporating Zeonex as a base material, the sensor achieves unparalleled sensitivity and minimal material loss, thereby establishing new benchmarks for alcohol detection technologies. Its distinctive design, featuring rectangular air holes and an asymmetrical structure, not only enhances birefringence but also amplifies its sensitivity, guaranteeing superior performance that outstrips existing methods. The sensor’s operational advantages include its ability to detect alcohol at extremely low concentrations, its high speed of detection, and its resistance to environmental factors such as temperature and humidity. Beyond simple alcohol detection, the sensor serves as a versatile instrument with the potential for widespread application in sectors that demand dependable and efficient detection mechanisms, highlighting its adaptability and the broad scope of its use. This article not only provides a detailed overview of the sensor’s technical specifications and operational advantages but also places it within the broader landscape of technological innovation, signaling the dawn of a new chapter in substance detection and analysis.
