ABSTRACT:
A photonic proximity sensor and photonic sensor system are provided. The photonic proximity sensor includes a first light source, a second light source, and a magneto-optic device. The magneto-optic device receives light emitted from the first and second light sources, and is responsive to variations of a magnetic field to rotate the light from one of the sources significantly more than the light from the other light source.
