The use of plastics can be dangerous due to the numerous industrial chemicals they contain. Di(2‐ethylhexyl) phthalate (DEHP), bisphenol A (BPA), and bisphenol S (BPS) are three detrimental organic chemicals that are used in the plastic industry. In this work, a highly sensitive photonic crystal (PCL) sensor is theoretically proposed and numerically simulated as a detector for DEHP, BPA, and BPS organic chemicals. The proposed PCL is a 1D that has the structure (GaAs/Si3N4/TiN)N/cavity layer/(GaAs/Si3N4/TiN)N, where N is the number of unit cells (UCs). The DEHP, BPA, and BPS analytes are assumed to be separately infiltrated into the cavity layer between two equal numbers of the UCs. The transmission spectra of the PCL are studied using the transfer matrix (TrMx) technique. The most important performance parameter is sensitivity so we have focused on it. A considerable sensitivity enhancement is obtained by raising the defect layer thickness and incidence angle. High sensitivities of 2350.51, 2168.45, and 2042.08 nm RIU−1 are obtained for DEHP, BPA, and BPS, respectively. In the results obtained, the way can be paved for a simple technique to detect chemical compounds.

Structural color is a remarkable physical phenomenon that exists widely in nature. Unlike traditional color rendering methods, they are realized mainly through micro/nanostructures that interfere, diffract, scatter light, and exhibit long‐life and environmental‐friendly color effects. In nature, a few organisms use their color‐changing system to transmit information, such as courtship, warning, or disguise. Meanwhile, some natural inorganic minerals can also exhibit structural colors. Learning from nature, scientists have achieved large‐scale structural color design and manufacturing technology for artificial photonic crystals. Photonic crystals have a unique microstructure that forms a band gap under the action of the periodic potential field, consequently causing Bragg scattering due to the periodic arrangement of different refractive index media within them. Because of the apparent photonic band gap and the ability to form local photons at crystal defects, photonic crystals have been extensively studied in recent years and have broad application prospects in photonic fibers, optical computers, chips, and other fields. In this review, the research, properties, and applications of photonic crystals in recent years are presented, as well as insight into the future developments of photonic crystals.
