Journal ArticleDOI

An introduction to InP-based generic integration technology

TL;DR: The paper explains the concept of generic photonic integration technology using the technology developed by the COBRA research institute of TU Eindhoven as an example, and it describes the current status and prospects of generic InP-based integration technology.
Proceedings ArticleDOI

Eigenmode expansion methods for simulation of optical propagation in photonics: Pros and cons

TL;DR: The EME (EigenMode Expansion) technique is a powerful method for calculation of electromagnetic propagation which has been well known amongst academic environments and also in microwave fields, representing the electromagnetic fields everywhere in terms of a basis set of local modes as mentioned in this paper.
Journal ArticleDOI

Low-Crosstalk Fabrication-Insensitive Echelle Grating Demultiplexers on Silicon-on-Insulator

TL;DR: In this paper, the authors report about design, fabrication, and testing of echelle grating demultiplexers in the O-band for silicon-based photonic integrated circuits.
Journal ArticleDOI

An FDTD method for the simulation of dispersive metallic structures

TL;DR: In this article, a formulation of the FDTD time-domain method for the simulation of metallic structures is presented, where the frequency dependent dielectric function of metals is approximated by a combined Drude-Lorentzian multi-pole expansion and fitting errors of only a few percent.
Journal ArticleDOI

Accurate near-field calculation in the rigorous coupled-wave analysis method

TL;DR: In this paper, the authors investigated the accuracy with which the electromagnetic near-field can be calculated by using RCWA and explained the observed slow convergence and numerical artifacts from which it suffers, namely unphysical oscillations at material boundaries due to the Gibbs phenomenon.
