Nano-displacement measurements using spatially multimode squeezed light

Year: 2004

Type: article

Abstract: We demonstrate the possibility of surpassing the quantum noise limit for simultaneous multi-axis spatial displacement measurements that have zero mean values. The requisite resources for these measurements are squeezed light beams with exotic transverse mode profiles. We show that, in principle, lossless combination of these modes can be achieved using the non-degenerate Gouy phase shift of optical resonators. When the combined squeezed beams are measured with quadrant detectors, we experimentally demonstrate a simultaneous reduction in the transverse x - and y -displacement fluctuations of 2.2 and 3.1 dB below the quantum noise limit.
