Abstract
An electric field sensor may include an atomic vapor cell and a plurality of lasers configured to excite atoms in the vapor cell from a low-energy state to a high-energy state. The sensor may be configured to split signals from the plurality of lasers into multiple polarized signals. The polarized signals may be transmitted through the atomic vapor cell. A subset of the polarized signals may be received by photodetectors after the subset exits the vapor cell. Based on signals from the photodetectors, the electric field sensor may determine an angle of arrival and polarization information about an electric field that is incident upon the atomic vapor cell.
