Abstract
A threshold magnetometer includes a vertical cavity surface-emitting laser with a first material that is disposed in one of the layers. The first material is configured as an absorbent material or emission material to light propagating in the optical resonator. As an absorbent material, the first material absorbs light when exposed to radio frequency (RF) radiation at one or more resonant frequencies. As an emission material, the first material intensifies light when exposed to RF radiation at one or more resonant frequencies. The resultant intensity change can be detected and used to determine characteristics of an external magnetic field.
