We report the development of the visored shutter structure for astronomical instrument and the electrostatic operation in a 140K cryogenic environment without thermo-mechanical failure.
We report on the experimental demonstration of single-photon source based on a single InAs quantum dot emitting in the telecommunication band. The low-density quantum dots grown by epitaxial method are embedded in an as-etched pillar structure. Photoluminescence spectrum of a single InAs quantum dot exhibits intense and narrow emission lines. Photon antibunching behavior is clearly observed using...
We report a new structure of electrostatically addressable and latchable multi-slit shutter array for the astronomical spectrograph with an improved optical and electromechanical performance using the electroplated visors.
