Abstract
Methods and sensors for detecting the presence and/or concentration of an analyte are disclosed. In one aspect, a sensing element for use in a sensor is disclosed. The sensing element comprises a resonant cavity device configured to emit optical radiation at an initial power level, a sensing layer exhibiting an initial refractive index, and a detector. The sensing layer is configured to absorb or adsorb an analyte and, in response to absorbing or adsorbing the analyte, exhibit a modified refractive index that differs from the initial refractive index. The resonant cavity device is further configured to, in response to the sensing layer absorbing or adsorbing the analyte, emit optical radiation at a modified power level based on the modified refractive index. The detector is configured to detect the modified power level.
