Analyzing multilayer optical waveguide with all nonlinear layers

Abstract

We propose a general method for analyzing a multilayer optical waveguide with all nonlinear layers. This general method can be degenerated into some special cases, such as symmetric or asymmetric nonlinear optical waveguide structures, the intensity-dependent refractive index with self-focusing nonlinear medium, hollow waveguides, and multilayer systems. Based on this general method, the analysis and calculation of complicated multilayer optical planar waveguides can be achieved easily. The analytical and numerical results show excellent agreement.

Analyzing the Multilayer Optical Planar Waveguides With Double-Negative Metamaterial

“…Studies of TE wave propagating on the multilayer systems in linear/nonlinear have attracted a great deal of interest in the past two decade [29][30][31][32][33][34][35][36]. Wu et al developed accurate calculations for multilayer systems with DPS materials, as multilayer planar waveguide with nonlinear cladding [37], multilayer planar waveguide with nonlinear cladding and substrate [38], multilayer planar waveguide with a localized arbitrary nonlinear guiding film [39], multilayer planar waveguide with all nonlinear guiding film [40], and multilayer planar waveguide with all nonlinear layers [41]. The complete set of modes of all possible solutions for the TE wave in the three-layer planar waveguide with photonic metamaterial was analyzed and disused [42].…”

Analysis and Calculations of Forbidden Regions for Transverse-Electric-Guided Waves in the Three-Layer Planar Waveguide with Photonic Metamaterial

“…Guided modes in the NIM planar waveguide with " f f > " c c and j f j > c would be forbidden in some regions. The modal theory can be used to analyze the evolutions of optical light waves in the conventional linear and non-linear planar waveguide structures [9][10][11]. In this work, the modal theory is used to explain the forbidden region in the NIM planar waveguide.…”

A General Rule for Designing Multibranch High-Order Mode Converter

“…These step-waveguide segments can be analyzed by the method proposed in Refs. [18][19][20][21]. Figure 2 shows the high-order mode converter.…”

“…The final distances D of each adjacent guiding channel can be calculated by mode theory [18][19][20][21]. The lengths of L 2 and L 4 can be determined by the branching angle and the final distances.…”

“…The device would be used in the complement operation in all-optical data computing system. We use the modal theory [18][19][20][21] to analyze the proposed structure rigorously. For reducing the calculational processes, we presented the general design principles to study this structure.…”
