A quartz crystal oscillator that reduces the noise floor over commercial crystal oscillators by nearly an order of magnitude for the first time in 15 years has been demonstrated by collaborating researchers from the FEMTO-ST Institute, CNRS in France; the Academy of Sciences in the Czech Republic; and Oscil-loquartz in Switzerland. The 5 MHz crystal double-oven prototype, which has a flicker frequency modulation (FFM) floor of 2.5 × 10−14, opens the door to ultra-high stability oscillators for telecommunications, instrumentation and space applications.
