Rigorous characterization of photonic devices by finite element method

Abstract

A review on the characterisations of photonics devices by using the frequency domain modal solution, junction analysis and beam propagation methods and additionally time-domain approach, but all based on the numerically efficient finite element method is presented. Numerically simulated results for various photonic devices such as uniform optical waveguides, photonic crystal fibres, high-speed optical modulators, spot-size converters, compact power splitters, metalclad terahertz waveguides, photonic crystals and nonlinear acousto-optical interactions in optical waveguide are presented.

Process engineering study of photonic nanojet from highly intense to higher propagation using FDTD method

“…Theoretical investigations are mainly employed to know the behavior of change in light due to the desired structure. There are several methods employed to compute the solution of electromagnetic waves propagated from a finite structure such as transfer matrix method (TMM) [28], plane wave expansion (PWE) method [29], finite element method (FEM) [30], Boundary element method (BEM) [31], multiple multipole method (MMP) [7,8], finite difference time domain (FDTD) method [1][2][3][4][5][6][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] etc. Though there are several methods adopted for computation purpose, however FDTD method is frequently used because of user friendly simulation packages available in the market and to avoid empirical calculations [32].…”
