Nanolaser
A nanolaser is a laser that has nanoscale dimensions. The nanolaser concept was developed by Mark Stockman at Georgia State University in 2003.
These tiny lasers can be modulated quickly and, combined with their small footprint, this makes them ideal candidates for on-chip optical computing. The intense optical fields of such a laser also enable the enhancement effect in non-linear optics or surface-enhanced-raman-scattering (SERS), and therefore paves the way toward integrated nanophotonic circuitry.
