Abstract
An electro-optical devicecomprises a bodyof a semiconductor material, such as silicon. A light sourceis formed integrally in the body. The device comprises an associated light detectorand an optical path providing parthaving a refractive index and extending between the light sourceand the detectorto provide an optical pathhaving a path length. A sensorcooperates with the optical path providing partand is configured to modulate light emitted by the light sourceby changing at least one of light absorption characteristics in the optical path by exposing a medium in the optical path to the emitted light, the path length and the refractive index.
