Their unique physical properties resulting from the low symmetry in-plane crystal structure and the prospects of their application in nanoelectronics and nanophotonics, as well as piezoelectric devices and thermoelectrics are discusseddoi:10.1016/j.nantod.2016.10.003He...
As represented by the GSM beam, low-coherence light sources constitute a fascinating category of light sources that emit optical waves with a distinctive blend of attributes, setting them apart from their high-coherence and incoherent counterparts. The development of low-coherence light sources has at...
Based on this perspective, we employ a model of two coupled driven oscillators, which has been successfully used to describe fano resonances, optical EIT, Borrmann and Kerker effects, and parity–time symmetry breaking4,19,40, to describe the CMA metasurfaces in this work. The resonance of ...
rotational symmetry, and chirality. In general, the absence of mirror symmetry in metasurfaces building blocks renders chirality [18]. Chiral structures are considered to interact differently with different input spin states and the optical responses that are sensitive to handedness...
(b) Calculated electronic energy band structure along the symmetry directions of the Brillouin zone (G–Y– C–X–G) and the projected density of states (PDOS) of the optimized structure of ML T iS3. The direct bandgap Eg of ML T iS3 is indicated by the red arrows. Reprinted...
To achieve circular dichroism, it is necessary to simultaneously break then-fold rotational (n > 2) and mirror symmetries for a two-dimensional meta-atom [40]. However, the symmetry-breaking effect for circular dichroism in microwave frequency is relatively slight due to the inadequate losses...
5 Realizing Mid-IR to THz nanophotonics and metamaterials: brief perspective From the preceding Sections, it is apparent that SPhP materials can provide the basis for a wide array of potential nanophotonic or metamaterial applications. In particular, the dramatically higher Q’s exhibited by SPhP ...
These exceptional characteristics highlight the promising nature of low‐symmetry TlSe as a novel material for ultrafast dual‐band nanophotonics. Furthermore, this work provides fundamental insights into anisotropic carrier dynamics, including effective mass‐dependent cooling and many‐body ...

Second-order nonlinearity can be introduced by breaking the symmetry of a crystal12,13 or heterogeneously integrating a non-centrosymmetric material14,15. Alternatively, photonic circuits may be built directly from a χ(2) nonlinear material such as aluminum nitride16 or lithium niobate (LN). LN ...
