UCSB lasers marry quantum dots and silicon . 03?Mar?2014 Combination of high-performance devices and low-cost base material suggests cheaper photonic integration. Quantum dots and silicon: perfect match? A University of California, Santa Barbara (UCSB) research team led by John Bowers and Arthur Gossard is developing a new way of producing high-performance lasers on low-cost silicon substrates, in work that could lead to much cheaper photonic devices for communicatio...
