Summary: This paper investigates the extensions of Rayleigh-Bloch waves above the cutoff frequency using the discrete spectrum of a transfer operator. The study reveals the complex behavior of Rayleigh-Bloch waves at frequencies above the cutoff, showing connections with the Neumann and Dirichlet trapped modes before embedding in the continuous spectrum. A homotopy method with an artificial damping term is proposed to identify the discrete spectrum close to the embedding. The paper also discusses the disappearance and reappearance of Rayleigh-Bloch waves at different frequencies for small and large cylinders, which is connected to finite-array resonances.

Summary: This study investigates the impact of Bloch surface wave excitation on the temporal characteristics of short optical pulses in dielectric multilayers. It is found that resonant excitation leads to the splitting of the reflected pulse into leading and exponentially decaying trailing parts.

Summary: An eigenvalue model is developed to study the band structure of water surface waves in the presence of an infinite array of periodically arranged scatterers. The scattering of waves over arbitrary terrain or bodies is described as a boundary value problem of the Laplace equation, and the boundary integral equation is transformed into an eigenvalue problem using the boundary element method to obtain the band structure. The proposed model is validated and its accuracy is confirmed by comparing with existing models and experimental reflection coefficients. The dependence of the stopbands on the relative size of scatterers and relative water depth is investigated and analyzed.

Summary: This article focuses on the generation of nonclassical states of light in integrated optical devices, particularly Gaussian states beyond the range of low-gain, single photon pairs described by perturbation theory. Starting from Maxwell's equations, a unified formulation is presented for comparing stimulated and spontaneous experiments in ring resonators and nanophotonic waveguides, enabling the calculation of the quantum states of light generated in high-gain nonlinear quantum photonic experiments.

Summary: We study the generation of photon pairs through spontaneous four-wave mixing in a structure consisting of two linearly uncoupled resonators. Energy can only be transferred from one resonator to another through a nonlinear interaction. We consider the case of two racetrack-shaped resonators connected by a coupler, and derive analytic expressions for the pair-generation rate. We compare these results with that achievable in a single-ring resonator.

The probability of single soliton formation is increased by more than two times using backward tuning of the laser, and the increased thermal stability enables soliton formation by thermal tuning of the whole sample, keeping the laser at a fixed frequency.

Summary: This paper discusses the implementation of third-order parametric down-conversion (TOPDC) in integrated photonic systems. The rates of TOPDC in nonresonant and resonant platforms are derived, showing the scaling with experimental parameters. It is found that nonresonant platforms are more suitable for spontaneous TOPDC (SpTOPDC), while resonant platforms are better for stimulated TOPDC (StTOPDC). A sample calculation is presented, demonstrating the feasibility of observing StTOPDC with current fabrication technology and the potential for integrated SpTOPDC in the future with improved platform design.
