TL;DR: In this article, the authors demonstrate bidirectional and coherent conversion between microwave and light using collective spin excitations in a ferromagnet, where microwave photons and magnons in the respective modes are strongly coupled and hybridized.

TL;DR: The spin-orbit coupled nature of the WGM photons, their geometrical birefringence, and the time-reversal symmetry breaking in the magnon dynamics impose the angular-momentum selection rules in the scattering process and account for the observed phenomena.

TL;DR: Brillouin scattering of photons in the whispering gallery modes by magnons in the magnetostatic modes is experimentally investigated, finding that the conservation of the orbital angular momentum results in different nonreciprocal behavior in the Brillouin light scattering.

TL;DR: In this article, a single-photon source is integrated on a glass-clad silicon photonic waveguide processed by a CMOS foundry using transfer printing, which enables them to integrate heterogeneous optical components in a simple pick-and-place manner and thus assemble them after the entire CMOS process is completed.

TL;DR: In this paper, a selection rule that dictates the exchange of orbital angular momenta between the vortices was shown to be responsible for the experimentally observed non-reciprocal Brillouin light scattering.
