    • Nine-channel wavelength tunable single mode laser array based on slots 

      DONEGAN, JOHN; NAWROCKA, MARTA; GUO, WEI-HUA (2013)
      A 9-channel wavelength tunable single-mode laser array based on slots is presented. The fabricated laser array demonstrated a threshold current in a range of 19~21 mA with the SOA unbiased at 20?C under continuous wave ...

    • Single mode lasers based on slots suitable for photonic integration 

      DONEGAN, JOHN; LU, QIAOYIN; NAWROCKA, MARTA; GUO, WEI-HUA (2011)
      The re-growth free single mode lasers based on etched slots suitable for photonic integration are presented in this paper. The fabricated 650?m long laser exhibits a threshold current and a slope efficiency of about 32mA ...
