Quantum dot laser

‘Quantum dot’ lasers present an opportunity to reduce the cost of photonics devices for telecommunications, according to the University of California at Santa Barbara (UCSB). Usign photonics had often been prohibitively expensive in most cases due to the initial costs even though photonics is often many times more energy efficient than conventional electronics.
