Optical Measurements
Challenge :
Quantum optics often involve not only low temperatures and high-magnetic fields , but also scarce signals from single photon emitters , which may be randomly scattered across the substrate . Hence , a typical measurement requires repeatable insitu motion to locate emitters , and , once there , long-term stability due to long acquisition times . Furthermore , mesoscopic samples like nanowires or 2D materials require large scan ranges in extreme environments .
attocube ´ s solution :
attocube cryogenic nanopositioners enable in-situ movements over macroscopic distances ( cm range ) with step size in the range of tens of nm , and without drift ( achieving ground positioning ). They are thus perfectly suited for selecting best singlephoton sources and consequent measurements on them over months .
