Seismic noise is one of the noise sources limiting the performance of earth-bound interferometric gravitational wave detectors. To enhance the operation time of future detectors, new sensors for active stabilization of the mirror displacement are required. Commercial sensors are heavy, bulky and not vacuum compatible, where our design, based on an all-glass opto-mechanic oscillator with an interferometric read-out, resolves these constraints. The concept, design and first tests of the oscillators will be presented.
