Observation of Dyakonov Surface Waves

Physical Review Letters, 2009
Summary form only given. A special type of surface wave was predicted by M. I. Dyakonov in 1988. Such waves exist under special conditions at the interface of transparent anisotropic materials, and hens they are lossless.

Spin-Dependent Visible Dyakonov Surface Waves in a Thin Hyperbolic Metamaterial Film

Nano Letters, 2022
A Dyakonov surface wave offers a promising way of guiding light in two dimensions with almost no loss but also additional freedom of modulation through the anisotropy at the interface. Here we experimentally demonstrated a spin-dependent Dyakonov surface

Optical Dyakonov surface waves at magnetic interfaces

Optics Letters, 2005
We address the existence and properties of lossless surface waves that form at interfaces between magnetic and birefringent media. We show that the angular domain of existence of Dyakonov surface waves for magnetic interfaces is significantly larger than

Dyakonov surface waves in lossy metamaterials [PDF]

Optics Communications, 2015
We analyze the existence of localized waves in the vicinities of the interface between two dielectrics, provided one of them is uniaxial and lossy. We found two families of surface waves, one of them approaching the well-known Dyakonov surface waves ...

Lossless directional guiding of light in dielectric nanosheets using Dyakonov surface waves

Nature Nanotechnology, 2014
Guiding light at the nanoscale is usually accomplished using surface plasmons(1-12). However, plasmons propagating at the surface of a metal sustain propagation losses. A different type of surface excitation is the Dyakonov surface wave.

Transition from Dyakonov and Dyakonov-Tamm surface waves to surface-plasmon-polariton waves induced by temperature [PDF]

Nanostructured Thin Films X, 2017
Temperature-induced changes in the propagation of electromagnetic surface waves guided by the planar interface of a temperature-sensitive isotropic material (namely, InSb) and a temperature-insensitive anisotropic material were investigated theoretically in the terahertz frequency regime. Two types of anisotropic partnering material were considered: (i)

High-phase-speed Dyakonov surface waves

Journal of Nanophotonics, 2021
The canonical boundary-value problem for Dyakonov-surface-wave propagation in a fixed direction guided by the planar interface of a uniaxial dielectric material and an isotropic nondissipative dielectric material was solved. Both partnering materials were taken to be homogeneous and the constitutive parameters for both to lie within the ranges of ...

Dyakonov Surface Waves in Twisted Confined Media

Conference on Lasers and Electro-Optics, 2021
We theoretically predict the existence of Dyakonov-like surface waveguide modes in the planar interfacial waveguide between two uniaxial dielectrics and Dyakonov surface cavity modes in the interface of two anisotropic dielectrics with rectangular cross-sections.

Dyakonov-like surface waves in anisotropic cylindrical waveguides [PDF]

Physical Review B, 2020
Dyakonov surface waves are a well-known example of surface electromagnetic waves propagating along a plane interface between isotropic and anisotropic dielectric media. Here, we investigate the spectrum and radiative losses of Dyakonov waves at the curved interface considering both cases of "positive" and "negative" curvature of anisotropic medium.
