Quantum results in macroscopic structures have lengthy been a fascination for researchers. during the last decade mechanical oscillators have emerged as a number one method of selection for plenty of such experiments. The paintings suggested during this thesis investigates the results of the radiation-pressure strength of sunshine on macroscopic mechanical constructions. the elemental method studied is a mechanical oscillator that's hugely reflective and a part of an optical resonator. It interacts with the optical hollow space mode through the radiation-pressure strength. either the dynamics of the
mechanical oscillation and the homes of the sunshine box are changed via this interplay. The experiments use quantum optical instruments (such as homodyning and down-conversion) with the target of eventually exhibiting quantum habit of the mechanical middle of mass movement.
Of specific worth are the particular descriptions of a number of novel experiments that pave the best way in the direction of this target and are already shaping the sector of quantum optomechanics, specifically optomechanical laser cooling and powerful optomechanical coupling.

1 Working principle of the fiber interferometer. A fiber tip is positioned above the mechanical resonator, which modulates the phase φ of the light field upon back-reflection into the fiber. The modulation can either be detected by observing the amplitude of the beam, as the fiber tip partially reflects light (around 4 %), which then interferes with the signal reflected off the resonator, or by performing a homodyne measurement shift upon reflection off the mirrors can be stored in the cavity, which makes it a frequency filter for light.
