Query: Interference control of perfect photon absorption in cavity quantum
  electrodynamics   We propose and analyze a scheme for controlling coherent photon transmission
and reflection in a cavity-quantum-electrodynamics (CQED) system consisting of
an optical resonator coupled with three-level atoms coherently prepared by a
control laser from free space. When the control laser is off and the cavity is
excited by two identical light fields from two ends of the cavity, the two
input light fields can be completely absorbed by the CQED system and the light
energy is converted into the excitation of the polariton states, but no light
can escape from the cavity. Two distinct cases of controlling the perfect
photon absorption are analyzed: (a) when the control laser is tuned to the
atomic resonance and creates electromagnetically induced transparency, the
prefect photon absorption is suppressed and the input light fields are nearly
completely transmitted through the cavity; (b) when the control laser is tuned
to the polariton state resonance and inhibits the polariton state excitation,
the perfect photon absorption is again suppressed and the input light fields
are nearly completely reflected from the cavity. Thus, the CQED system can act
as a perfect absorber or near perfect transmitter/reflector by simply turning
off or on of the control laser. Such interference control of the coherent
photon-atom interaction in the CQED system should be useful for a variety of
applications in optical logical devices.
