Use of the magnetooptical properties of a lightguide to measure weak microwave fields
Abstract
The feasibility of using the Faraday effect to measure extremely weak microwave fields and low microwave power densities is examined. The loss level that has been achieved in optical fibers (a few decibels per kilometer) makes it possible to use a relatively prolonged interaction of a light wave with the magnetic component of the microwave field to achieve a large rotation of the polarization plane of the light wave. The sensitivity of this method for measuring low microwave power density is estimated.
