It is known that for the isolated dielectric cylinder waveguide, the modes with a certain
angular symmetry cannot be guided ones (without loss by radiation) if their frequency is …

The dimensionality of a physical system is one of the major parameters defining its physical
properties. The recently introduced concept of synthetic dimension has made it possible to …

We have studied the optical oscillation and tunneling of light waves in optical waveguide
ladders (OWLs) formed by two coupled planar optical waveguide arrays. For the band …

Band structures are intrinsically influenced by the mode interaction in waveguide array,
which can support many intriguing phenomena such as negative refraction, on-chip lensing …

Beyond the constraints of conservative systems, altering wave propagation frequency
emerges as a crucial factor across diverse physical domains. This Letter demonstrates bi …

Anomalous optical Bloch oscillation in waveguide arrays are investigated within the
generalized Coupling Mode Model (CMM). This model takes into account the next neighbor …

The light Bloch oscillations in the array of optical waveguides are investigated based on the
electrodynamics of continual approach. The array possesses a step-like refractive index …

We study the optical oscillations of supermodes in planar optical waveguide arrays with a
parabolically graded propagation constant in individual waveguide interacting through …

We consider one-dimensional chains of two-level quantum systems coupled via tunneling.
The chain is driven by the superposition of dc and ac fields in the strong coupling regime …

We present a theoretical study on Bloch oscillations in a helicoidal lattice with the first
neighbor hopping and a selected N-th neighbor hopping. By the use of a simple variational …
