The ink was hardly dry on his new contract as assistant professor of electrical and computer engineering at Lehigh, when Nelson Tansu announced a breakthrough in his research into high-performance lasers.
In two recent issues of Applied Physics Letters (APL) - on July 7 and Sept. 29, Tansu and other collaborating researchers reported the best threshold values to date for near-infrared-range (with an emission wavelength of 1300-nm), indium-gallium-arsenide-nitride (InGaAsN) lasers emitting from a quantum well.
Tansus group also achieved the best threshold values yet for near-infrared-range quantum-well (QW) lasers operating under continuous-wave conditions at temperatures up to 100 degrees C.

Researchers have developed an ultrafast light-emitting device that can flip on and off 90 billion times a second and could form the basis of optical computing.
Joint BioEnergy Institute study identifies bacterial protein that is key to protecting rice against bacterial blight
A bacterial signal that when recognized by rice plants enables the plants to resist a devastating blight disease has been identified by a multi-national team...
Researchers in the Cockrell School of Engineering at The University of Texas at Austin are one step closer to delivering smart windows with a new level of energy efficiency, engineering materials that allow windows to reveal light without transferring heat and, conversely, to block light while allowing heat transmission, as described in two new research papers.
By allowing indoor occupants to more precisely control the energy and sunlight passing through a window, the new materials could significantly reduce costs for...
Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. Argonne Leadership Computing Facility (ALCF) researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code.
While reviewing the simulation results of a promising new lubricant material, Argonne researcher Sanket Deshmukh stumbled upon a phenomenon that had never been...
A NASA camera on the Deep Space Climate Observatory (DSCOVR) satellite has returned its first view of the entire sunlit side of Earth from one million miles away.
The color images of Earth from NASA's Earth Polychromatic Imaging Camera (EPIC) are generated by combining three separate images to create a...
