Major breakthrough: Hypermaterials simultaneously enhance and capture light Application of ultra-fast LED lights
According to the Science Daily, a research team at the City University of New York has successfully demonstrated how to increase light emission and capture light from metamaterials embedded in nanoluminescent crystals. The study, led by physicist Dr. Vinod Menon, led to a range of applications, including ultra-fast LED lights, nano-scale lasers and efficient single-photon sources.
In the demonstration, the research team used metamaterials with hyperbolic dispersion to improve the light emission characteristics of nanocrystals, and designed an effective light extraction scheme. “Using metamaterials in an optical background means you can control the light and determine the characteristics of the light you want in the medium,” says photonician expert Professor Mano, who specializes in nanoscale light-substance interactions. control.
Although other research groups have shown that they can enhance light emission in such systems, Professor Mano's own research team has achieved this in the past, but the past results do not make much sense, mainly because light is not easy. Launching from such a system makes its practical application a problem. The current study has alleviated this problem and has taken the first step toward developing an actual light emitter based on metamaterials.
“Our research has both enhanced light emission and extracted light,” adds Professor Mano. His research team also includes doctoral students Tal Galfsky and H.N.S. Krishnamoothy. In addition, the research team includes scientists from the University of Alberta in Canada and Purdue University in Indiana, USA. Part of the research was conducted at the Functional Nanomaterials Center at the Booker Haven National Laboratory. This article was published in the journal Optical Journal.
