Supplies readers with the basic knowledge and guidance for the
application of new lasers and light-emitting devices. The first part of
the book discusses the generation of sub-shot-noise light in macroscopic
pn junction light emitting devices, the second part is on the
application of squeezed light in high-precision measurement, the third
part concerns the Coulomb blockade effect in a mesoscopic pn junction
and generation of single photon states, and the last part is on the
detection of single photons using a visible light photon counter.
