  The intensity noise of nanolasers and nanoLEDs is analyzed for conventional
and quiet pumping of electrons into the active region. It is shown that
nanoLEDs with Purcell-enhanced emission rates, enabled by extreme dielectric
confinement, may be excellent sources of intensity-squeezed light within a
bandwidth of several gigahertz. The physics of intensity squeezing is
elucidated and it is shown that the parameter dependence can be explained by an
effective Fano factor.
