Abstract :
We report on the fabrication and characterization of flexible distributed-feedback (DFB) lasers made with CdSe/ZnS colloidal quantum dots. The laser cavity of these lasers is based on a submicron scale pattern replicated from a commercial DVD onto a photocurable flexible polymeric substrate followed by the drop-coating of a quantum dot solution. Typical laser threshold behavior and operation lifetime under ambient conditions are studied. Emission polarization and the effect of the pump polarization on device characteristics are also discussed.
