Theory of radiation-pressure-driven interferometers

Abstract
We review the theory of optical interferometers in which a light mirror is suspended to swing as a pendulum and can therefore respond to radiation-pressure forces. The basic principles are elaborated on by considering a two-mirror system, and optical bistability and mirror confinement are predicted. A three-mirror system is also described that is capable of producing a far higher level of mirror confinement. White- and ground-noise analyses are given.
