Non-paraxial beam propagation in nonlinear optical waveguides using complex Jacobi iteration Ghent University
We present the recently introduced beam propagation method using complex Jacobi iteration adapted for efficient modeling of non-paraxial beam propagation in nonlinear optical waveguides.
Modeling the optical properties of metallic nanoparticles Ghent University
Application of modified Padé approximant operators to time-domain beam propagation methods Ghent University
Modified Padé-approximant-based wide-angle beam propagators Ghent University
Comparative assessment of time-domain models of nonlinear optical propagation Ghent University
We present a comparative assessment of time-domain approaches for modelling nonlinear optical propagation, focussing on a finite-difference time-domain beam propagation method (TD-BPM) and the rigorous transmission line modelling (TLM) method. The assessment is carried out on the basis of reflection and transmission of non-stationary light beams propagating through the junction of linear and nonlinear waveguides.
Design of type-II interband cascade lasers for terahertz emission Ghent University
We report the design of type-II interband cascade (IC) lasers emitting at terahertz (THz) range. The band structures are obtained using an eight-band k center dot p finite difference method with strain effects, which accounts for the coupling between the conduction and valence bands. Also, a detailed analysis of the interband transition energy in the type-II IC laser structures as a function of layer thickness is carried out using the ...
