Abstract
This Small Business Innovation Research Phase I project is intended to investigate the feasibility of enhanced magneto-optic thin garnet films, capable of converting magnetic field intensity to optical data using Faraday polarization rotation, and fabrication of such films using a novel method of manufacturing all-dielectric metal oxides. This type of thin film is known as an "in-plane" film because the magnetization vector lies in the plane of the substrate and must be distinguished from the "out-of-plane" thick films that are used in large quantities in optical communications (e.g. for isolators and circulators), and in some electrical current sensors. With the projected film properties and proposed system design, it is estimated that magneto-optical imagers (MOIs) can resolve spatial magnetic features of less than 200 nm and magnetic field strengths of less than 100 nanotesla (which corresponds to electrical currents of less than 10
