  The future of quantum communication systems and quantum networks heavily rely
on the ability to fabricate and coherently control the conversion of photons
between different modes based on a solid-state plateform. In this work, we
propose and theoretically investigate a scheme to optomechanically control
coherent mode conversion of optical photons by utilizing two optically coupled
hybrid semiconductor microcavities containing a quantum dot (QD). One of the
microcavity is pumped by an external laser and the second cavity is driven by
light emitted by the QD that is embedded in the interface separating the two
microcavities. The semiconductor microcavities can be fabricated using
distributed Bragg reflectors (DBR) and can be made movable. We have
demonstrated that photon-mode-conversion efficiency can be coherently
manipulated by the optomechanical mode under appropriate conditions.
