Abstract

Sensor material is arranged to interact with input light and to asymmetrically alter a spectral distribution of the input light in response to presence of an external stimulus. A detector is configured to sense the altered input light and to generate at least one electrical signal comprising information about a shift in the centroid of a spectral distribution of the altered input light relative to a centroid of the spectral distribution of the input light.
