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."
When bad men combine, the good must associate; else they will fall one by one,
an unpitied sacrifice in a contemptible struggle.
