MRI COIL WITH WHISPER GALLERY MODE PHOTONIC SENSOR

摘要

A whispering gallery mode optical resonator (26) is constructed from an electro-optic material allowing direct electrical modulation of a light signal. Modulation frequencies of greater than the bandwidth of the modes (42) of the whispering gallery mode optical resonators are made possible by means of a resonance splitting technique that provides a second passband mode offset from the primary passband modes of the whispering gallery mode optical resonators to accommodate a modulation sideband (44).
