Brendan Roycroft

Biography

Dr. Roycroft has worked in the Tyndall National Institute, Ireland, since September 2001 and has interests in designing and testing novel telecoms lasers, green and red resonant cavity LEDs, and red and near infra-red VCSELs. Currently he is working on the Centre for Telecoms Value-chain-driven Research (CTVR) project, an industrially and nationally funded project between Alcatel/Lucent Technologies and all the major Irish universities, developing integrated tunable lasers for flexible network performance, and recently started became PI developing narrow linewidth tunable lasers for coherent telecommunications.
