DOI: 10.1002/andp.201800203

Abstract: The integration of neutral atoms with nanophotonic structures offer significant potential as a versatile platform to explore fundamental light-matter interactions as well as realizing novel quantum-optical devices. Here, we investigate the possibility of creating low-threshold… read more here.

DOI: 10.1038/nature20799

Abstract: In 1929, only three years after the advent of quantum mechanics, von Neumann and Wigner showed that Schrödinger’s equation can have bound states above the continuum threshold. These peculiar states, called bound states in the… read more here.

DOI: 10.1088/1555-6611/aa555c

Abstract: We fabricated polyvinyl alcohol (PVA) nanofibers doped with Rhodamine 6G laser dyes via an electrospinning technique, which were then excited by a pulsed laser for laser emission. The laser was observed at a low threshold… read more here.

DOI: 10.1364/ol.44.003669

Abstract: We experimentally demonstrate the lasing action of a new nanolaser design with a tunnel junction. By using a heavily doped tunnel junction for hole injection, we can replace the p-type contact material of a conventional… read more here.
