Abstract

A cryogenic sapphire oscillator1,2(CSO) exploits the low loss propertiesof sapphire at cryogenic temperatures to generate microwave signals withshort term fractional frequency stability below 10−15. If two CSOs arealigned orthogonally the beat frequency between the oscillators can beused to search for orientation dependent deviations in the speed of light.The sensitivity of such an experiment is dictated by the stability of thebeat frequency. Active rotation of the experiment can increase the effectivesensitivity although it can also induce extra systematic noise. Microwaveoscillators have been used in some of the most sensitive tests of Lorentzinvariance3,4and we will provide a brief outline of the design and principlesbehind such an experiment APA (American Psychological Assoc.)
