Periodic Photonic Structures Focus Spaser Light for Nanoscale Optics
BETHLEHEM, Penn., August 4, 2016 — Single-mode operation in plasmonic lasers has been demonstrated using a technique that implements distributed feedback in a novel way that couples the resonant surface plasmon polariton (SPP) mode of the laser to a highly directional far-field...
Carbon Spaser Could Zap Cancer Cells
MELBOURNE, Australia, April 21, 2014 — A carbon-based nanolaser could be used to zap cancer cells, or enable electronics small and flexible enough to be printed on clothing.
Stockman Elected SPIE Fellow
BELLINGHAM, Wash., March 7, 2014 — Mark Stockman has earned the designation of SPIE fellow for his work with theoretical nano-optics and nanoplasmonics.
Georgia State Creates Nano-Optics Center
ATLANTA, Dec. 16, 2013 — Georgia State University announced last week that it has created a research center to focus on developing nanotechnology tools and instruments, The Center for Nano-Optics. “Creation of the Center for Nano-Optics is an important next step for...
Smallest semiconductor laser breaks diffraction limit
AUSTIN, Texas – A plasmon-based laser too small to be seen by the naked eye emits continuous green wavelengths at low energy levels and cold temperatures while operating below the 3-D optical diffraction limit. Physicists at The University of Texas at Austin, in...
Nanolaser Operates Below 3-D Diffraction Limit
AUSTIN, Texas, July 26, 2012 — Growing a smooth layer of silver onto a silicon substrate has improved the performance of nanolasers, offering a breakthrough for emerging nanophotonic devices with applications ranging from computing to medicine.
Transformation Optics Bends all the Rules
Aug 1, 2011 — From invisibility cloaks to hyperlenses, and photovoltaic concentrators to superresolution microscopy, transformation optics makes big promises. In the same way that water flows can be manipulated using dams and channels, light can be made to...
The Ones to Watch: Nanolasers Are Breaking New Ground – and Fast
Jun 1, 2011 — Rapid advances in nanolaser research are making this area of photonics a very hot topic. Whether tackling high optical losses in nanocavities or achieving room-temperature operation, scientific groups worldwide are helping to bring the nanolaser...
For lasers, small and thin are in
NORFOLK, Va. – Lasers just keep getting smaller and smaller: Recently, only a couple of months after the report of the world’s thinnest laser, the world’s smallest laser was announced. Both developments barely precede the 50th anniversary of the laser, which will...
'Spaser' Nanolaser Realized
WEST LAFAYETTE, Ind., Aug. 17, 2009 – By harnessing clouds of electrons called surface plasmons instead of photons, engineers at Purdue University overcame a barrier preventing lasers from being integrated into electronic circuits. Their nanolaser, the "spaser," is the first of its kind...
