Phase-enhanced nonreciprocal photon-phonon conversion via coupled optomechanical cavities
Divya Mishra, Parvendra Kumar
Nonreciprocity, characterized by direction-dependent signal propagation, is fundamental to technologies such as isolators, signal routing, and precision sensing. This letter theore…

Effects of phase-gradient on the nonadiabatic dynamics and photon-phonon conversion in one-dimensional array of optomechanical cavities
Divya Mishra, Parvendra Kumar
Manipulation of photonic and phononic coupling in the coupled cavities plays a crucial role in the development of nonreciprocal devices and photon-phonon conversion. Here, we theor…

Effects of cavity-mediated processes on the polarization entanglement of photon pairs emitted from quantum dots
Mukesh Kumar Samal, Divya Mishra, Parvendra Kumar
Semiconductor quantum dots are among the best sources of on-demand entangled photon pairs. The degree of entanglement, however, is generally limited by the fine structure splitting…
