摘要

Today, the advancement of suitable detectors for quick and precise discovery of explosives is a serious necessity for numerous safety and security purposes. Here, a novel trend is presented that employs a photonic crystal fiber device (PCFD) structure for the recognition of various explosives including nitroglycerin explosive (NGE), trinitrotoluene explosive (TTE), and royal demolition explosive (RDE). COMSOL Multiphysics software is employed and the finite element technique is operated to analyze the functioning of the offered PCFD. In the offered PCFD, we struggled to cover the whole fiber zone to exhaust the greatest volume of the incident waves which will boost the performance of the advanced PCFD. With ultra-high relative sensitivity of chosen explosives containing NGE (99.107), TTE (99.556), and RDE (95.940%), the offered PCFD demonstrates its extraordinary aptitudes. Furthermore, the suggested PCFD provides very low confinement loss and effective material loss values, which means tiny loss can happen. These characteristics emphasize its capability to accurately determine even the most slight modifications in the refractive index for the tested samples.
