Bistability in Microcavities with Incoherent Optical or Electrical Excitation
We consider a quantum well embedded in a zero-dimensional microcavity with a
sub-wavelength grated mirror, where the x-linearly polarized exciton mode is
strongly coupled to the cavity photon, while y-polarized excitons remain in the
weak coupling regime. Under incoherent optical or electric pumping, we
demonstrate polariton bistability associated with parametric scattering
processes. Such bistability is useful for constructing polaritonic devices with
optical or electrical incoherent pumping.Comment: 5 pages, 3 figure
