We present a method for describing nonlinear electromagnetic interactions in integrated
photonic devices utilizing an asymptotic-in/out field formalism. Our method expands upon …

A four-wave mixing Hamiltonian system on the classical as well as on the quantum level is
investigated. In the classical case, if one assumes the frequency resonance condition of the …

Photon pair generation in silicon photonic integrated circuits relies on four-wave mixing via
the third-order nonlinearity. Due to phase matching requirements and group velocity …

In this paper, classical and continuous variable (CV) quantum neural network hybrid
multiclassifiers are presented using the MNIST dataset. The combination of cutoff dimension …
