Ultrafast Silicon Lasers Aim at Communications Tasks
Researchers have demonstrated 1,310-nm lasers on a silicon substrate that operate in continuous-wave mode up to high temperatures and 1,550-nm lasers that operate modelocked to produce the ultrashort pulses at high repetition rates that are desirable for communications.
A new hybrid-silicon laser is aimed right at communications applications. The collaborators, led by John Bowers at the University of California, Santa Barbara (UCSB) and Mario J. Paniccia at Intel, have demonstrated 1,310-nm lasers on a silicon substrate that operate in continuous-wave (cw) mode up to high temperatures (105° C) and 1,550-nm lasers that operate modelocked to produce the ultrashort pulses at high repetition rates that are desirable for communications (Opt. Express 15, 11466).
