PROBLEM TO BE SOLVED: To provide a sensor for detecting the presence of chemicals and/or biological agents with high sensitivity, while minimizing the detection time. SOLUTION: A chemical detector for detecting predetermined chemicals includes an optical fiber and a polymer, having a high fractional free volume higher than about 0.1 that clads a certain of the optical fiber. The optical fiber is arranged within an optical resonator. The chemical detector, further includes a coherent light source that excites the optical resonator and a chemical signature detector that detects a predetermined chemical, based on the change in resonance attenuation or the refractive index of the optical fiber, based on the absorption of a predetermined chemical into the high intrinsic microporosity polymer cladding of the fiber.
