Ultra-short pulse: A comprehensive way of sensing pure solvents through hollow core photonic crystal fiber sensor

Chemicals like acetone, ethanol, hexane, isopropanol, and hexanol are essential components of our daily routines, serving critical functions in various industries and medical settings. Therefore, it is essential to perform thorough examinations to identify any contamination in these substances, which is crucial for preserving their high quality and confirming their appropriateness for different uses. The detection of these chemicals is done using a novel approach utilizing ultra-short pulses passed through Hollow-Core-Photonic Crystal Fiber based sensor. The fiber characteristics including the non-linear and dispersion parameters are used to sense the change in shape of the ultra-short pulse as the pulse travels through the HC-PCF. By implementing this approach, we've attained distinctive levels of compression sensitivity and power upsurge for the samples tailored to each specific input setup. A minimum compression sensitivity has been recorded as 24.5 % when the input power was 600W, resulting in an outstanding power upsurge of 719 W.
