Gain and lasing from CdSe/CdS nanoplatelet stripe waveguides

Gain and lasing from CdSe/CdS nanoplatelet stripe waveguides

ABSTRACT: Colloidal semiconducting nanocrystals are efficient, stable and spectrally tunable emitters, but achievable optical gain is often limited by fast nonradiative processes. These processes are strongly suppressed in slab-shaped nanocrystals (nanoplatelets), due to relaxed exciton Coulomb inte...
