The design method is described for a triangular lattice, its optical properties such as transmission spectrum and dispersion relation are calculated, and actual devices are then fabricated and demonstrated that they worked as optical waveguides.
Simulation results indicate that in order to shift the zero-dispersion wavelength near to 1.55 μm, the larger core radius is required in the triangular graded index optical fiber compared to the step index one which is useful from fiber fabrication view points.
In order to make a further insight into the influences of the triangular nanoribbons on the optical performance, we give a detailed calculation and analysis for the modified structure shown in Fig. 6a, which contains a trapezoidal nanoribbon with a same angle θ to the triangular nanoribbon in original structure.
In this context, a numerical model based on accurate solutions of Maxwell's equations is developed in order to study the impact of both interface texturization morphologies (triangular and grooves) on the optical absorbance and electrical performance.
Exploration of the optical properties of those triangular particles has shown that the surface plasmon bands frequency is strongly sensitive to the corner sharpness.
As shown in Fig. 2a, there are three acoustic and three optical phonon branches for the buckled triangular borophene.
The optical action potentials acquire a distinct triangular shape with a slow depolarization phase and drastically increased alternans magnitude.
One side of the optical film is made of micro triangular-pyramidal array (MTPA), and the other side is micro gapless hexagonal microlens array (GHMA).
We report the design of an AND optical logic gate based on two dimensional triangular lattice of air holes in Si.
We describe herein a systematic investigation on the optical properties of Ag, Au, and Cu triangular nanoprisms as a function of size and excitation wavelength using the discrete dipole approximation.
The influence of triangular grating used as a light trapping structure on the optical wave propagation within thin-film microcrystalline silicon (µc-Si H) solar cells is investigated.
