Cryogenic properties of optomechanical silica microcavities
Cryogenic properties of optomechanical silica microcavities
The quest for observing the zero point fluctuations of a macroscopic mechanical oscillator is one of the major objectives in modern optomechanics. If optical cooling techniques have recently allowed to actively cool down various macroscopic oscillators (micro-mirrors, toroidal micro-cavities, membranes or gram scale mirrors), they still have to be combined …
