DESCRIPTION:Join us for this PSI seminar with guest speaker Dr. Guy Whitw
 orth. Solution-processed semiconductor lasers have achieved much success
  across the nanomaterial research community. The ease of integration wit
 h other photonic components and the potential for upscaling using emergi
 ng large-area fabrication technologies (such as roll-to-roll) make these
  lasers attractive as low-cost photonic light sources that can find use 
 in a variety of applications\, including: integrated photonic circuitry\
 , telecommunications\, chemo-/bio-sensing\, security and lab-on-chip exp
 eriments. However\, room-temperature solution-processed lasers in the ne
 ar-infrared telecommunication bands for fiber-optic communications and e
 ye-safe LIDAR applications had remained unrealised prior to this work. I
 n this talk\, I will present our work with PbS colloidal quantum dot dis
 tributed feedback lasers\, where we have demonstrated tunable lasing bet
 ween 1.55??m to 1.65??m. Additionally I will present studies we have mad
 e on ways to reduce the lasing threshold of these devices and the curren
 t work we are perusing on core-shell heterostructures.\n\n\n\n
