These lasers are the single most important step towards building computer chips that use light instead of electricity for ultra-fast and efficient on- and off-chip communications. Producing electrically powered nanoscale lasers has proven to be one of the toughest tasks facing electronic and photonic engineers. Over the last few years we have created very small on-chip lasers, but they need to be powered by a large, off-chip laser. We have also produced electrically powered (i.e. self-contained) lasers, but they require very cold temperatures (...

Hi everybody!                 The entire modern science is hanging around the electricity. The back bone of all recent trends and advancement of science, is the discovery of constituent particles of atom. One among them is  ELECTRON. George Johnstone Stoney is the first person who introduced the name ELECTRON for negatively charged subatomic particle in the year 1891.           It was a big challenge to many Scientists to understand the electricity. When electricity was invented, no one knew about electron. It was mystery over few decades. (ref., http://www.kidsnewsroom.org/elmer/infocentral/frameset/inventors/franklin/index.html )            On April 30, 1897 Physicist John Joseph Thomson and his team identified the subatomic particle ELECTRON by a cathode rays investigations. First He named the stream of subatomic particles as corpuscle in Latin, meaning sm...
