Optomagnonic cavities have recently been emerging as promising
candidates for implementing coherent photon-magnon interactions, for
applications in quantum memories and devices, and next generation
quantum networks. A key challenge in the design of such cavities is the
attainment of high magnon-mediated optical-to-optical conversion
efficiencies, which could, e.g., be exploited for efficient optical
interfacing of superconducting qubits, as well as the practicality of
the final designs, which ideally should be planar and amenable to
on-chip integration. Here, on the basis of a novel time-Floquet
scattering-matrix approach, we report on the design and optimization of
a planar, multilayer optomagnonic cavity, incorporating a
cerium-substituted yttrium iron garnet thin film, magnetized in-plane,
and operating in the triple-resonant inelastic light scattering regime.
This architecture allows for magnon-mediated optical-to-optical
conversion efficiencies of about 5% under realistic conditions, which
is orders of magnitude higher than that attained in alternative
optomagnonic designs. Our results suggest a viable way forward for
realizing practical information inter-conversion, with high
efficiencies, between microwaves, strongly coupled to magnons, and
optical photons, as well as a platform for fundamental studies of
classical and quantum dynamics in magnetic solids and for the
implementation of futuristic quantum devices.
