It is shown that coherent superpositions of two oppositely polarized n-photon states can be created by postselecting the transmission of n independently generated photons into a single-mode transmission line. It is thus possible to generate highly nonclassical n-photon polarization states using only the bunching effects associated with the bosonic nature of photons. The effects of mode-matching...

We put forward the concept of an optomagnonic crystal: a periodically patterned structure at microscale based on magnetic dielectric, which can co-localize magnon and photon modes. The co-localization in small volumes result large values photon-magnon coupling single quanta level, opens perspectives for quantum information processing conversion schemes with these systems. study theoretically si...

The current study focuses on the modeling and analysis of acoustic scattering from an elastic membrane disc located in a cylindrical waveguide that may involve structural discontinuities. physical problem is governed by Helmholtz’s equation involves higher order boundary conditions at interfaces. Mode-Matching (MM) method conjunction with Galerkin formulation developed to solve governing value ...

Substructuring methods have been studied since 1960s. The modes of subsystems associated with the lowest frequencies are typically retained. This mode selection rule is largely heuristic. In this paper, we use a moment-matching analysis tool to derive a new mode selection criterion, which is compatible to the one recently derived by Givoli et al using Dirichlet-to-Neumann (DtN) map as an analys...

Second harmonic generation (SHG) can be used as a technique for controlling the spatial mode structure of optical beams. We demonstrate experimentally the generation of higher-order spatial modes, and the possibility to use nonlinear phase matching as a predictable and robust technique for the conversion of transverse electric modes of the second harmonic output. The details of this effect are ...
