| Abstract | ||||
| In this article, we propose a novel all-optical sensor based on photonic crystals for the detection of petrochemical liquids. The sensor is based on a square lattice of GaAs rods suspended in air, coupled by an optimized ring resonator. The sensor performance was evaluated by injecting various petrochemical products, such as petrol, kerosene, and diesel. The sensor exhibits high sensitivity, high transmission, ultra-compact size of 274 μm², very fast response time, and high throughput. These characteristics make this sensor a promising candidate for various petrochemical detection applications. | ||||
