Towards an ultra-stable optical sapphire cavity system for testing Lorentz invariance

Proceedings of the 46th Rencontres de Moriond and GPhyS Colloquium on Gravitational Waves and Experimental Gravity, La Thuile, Italy:419-420.

We present a design for an ultra-stable cryogenically cooled sapphire optical cavity system, with fractional frequency stability better than 1 x 10^-16 at one second integration time. We plan to use such ultra-stable cavities to perform a test of the isotropy of light propagation at the 10^-20 level.
