  We study theoretically the photon statistics of the field emitted from two
optically coupled semiconductor microcavities each containing a quantum well.
The emission is determined by the interplay between exciton-photon coupling in
each quantum well and internal interaction between the two optically coupled
microcavities. A high degree of coherent control and tunability via the quantum
well-cavity coupling strength and photon tunneling over the photon statistics
of the transmitted field can be achieved. We demonstrate that the optical
property of radiation emitted by one quantum well can be controlled by the
properties of the second quantum well. This result has the potential to be used
in quantum information processing. We show that the exciton-photon coupling
influences the polariton resonances in the intensity spectrum of the
transmitted field. The results obtained in this investigation has the potential
to be used for designing efficient controllable all-optical switch and high
sensitive optical sensor.
