Cooler Silicon Lasers Via Energy Harvesting

Light Licker writes "UCLA researchers have developed a way to cut power use and heat output from a silicon laser used for optoelectronics. Both have been problems because silicon absorbs too much light — producing high-energy free electrons that make heat. One of Intel's best silicon lasers produced 125 times more heat than usable light. The UCLA team added a diode to their laser which can harvest free electrons and use them to help power the circuit — simultaneously cutting heat output and power use."

    Look, its simple. If its an article about lasers, the oblig comment will involve how a cooler laser will make the shark more comfortable, not the overlords comment. The overlords comment is better saved for when somebody actually develops the shark-carrying robots that will destroy us all (using the 1,2,3:??,4:profit! model, of course).
