Thermal Noise in Precision Interferometry

Thermal noise in advanced optical systems has emerged as a significant impediment to further progress in precision metrology. This noise process encompasses a number of related effects, with prominent examples being Brownian noise and thermo-optic noise, the latter being the coherent sum of thermoelastic and thermorefractive noise components in optical materials. Thermal noise and its impact in precision optical systems has been investigated in terms of the underlying physics and means for minimization over the previous two decades. Significant progress has been realized in the theoretical understanding of the underlying mechanisms, as well as in modeling the effects at the systems level, and finally in characterizing the performance of various optical materials. We will outline the state-of-the-art in the field and describe its impact on quantum optomechanical systems, cavity QED experiments, narrow-linewidth lasers for optical clocks, and, most prominently, in gravitational wave detector design. The symposium will serve to educate interested parties on the fundamental scientific aspects as well as implications for advanced applications in precision metrology, outlining opportunities for materials scientists, physicists, and optical engineers interested in pursuing basic research efforts as well as the development of components and systems with reduced thermal noise.
