Abstract
Compact optical cavities can be combined with motion sensors to yield unprecedented resolution and SI-traceability in areas such as acceleration sensing and atomic force microscopy AFM, among others. We have incorporated Fabry-Perot fiber-optic micro-cavities onto low-loss monolithic fused-silica mechanical oscillators, demonstrating exquisite sensitivities better than 200am/rtHz in displacement, and acceleration sensing levels below 100 nano- g/rtHz over a 10kHz bandwidth. Similar tests have been conducted with novel fused-silica AFM sensors, reaching resolutions of 14fN. We will present our results on novel optomechanical systems that offer both, high sensitivity and direct SI-traceability in very simple and compact devices.
