Colloidal Semiconductor Quantum Dot Whispering-Gallery Microlaser – a Comparative Study of Two Approaches

Not Accessible

Your library or personal account may give you access

Abstract

The microlaser consists of a tapered-fiber-coupled fused-silica microsphere, with HgTe nanocrystals deposited on one tapered fiber. Compared to a microlaser having a coated microsphere, the lasing signal is cleaner and the cavity Q remains high.
