Benchmarking five numerical simulation techniques for computing resonance wavelengths and quality factors in photonic crystal membrane line defect cavities
Jakob Rosenkrantz de Lasson, Lars Hagedorn Frandsen, Philipp Gutsche +10
We present numerical studies of two photonic crystal membrane microcavities, a short line-defect cavity with relatively low quality () factor and a longer cavity with high .…
Modeling open nanophotonic systems using the Fourier modal method: Generalization to 3D Cartesian coordinates
Teppo Häyrynen, Andreas Dyhl Osterkryger, Jakob Rosenkrantz de Lasson +1
Recently, an open geometry Fourier modal method based on a new combination of an open boundary condition and a non-uniform -space discretization was introduced for rotationally…
On the theory of coupled modes in optical cavity-waveguide structures
Philip Trøst Kristensen, Jakob Rosenkrantz de Lasson, Mikkel Heuck +2
Light propagation in systems of optical cavities coupled to waveguides can be conveniently described by a general rate equation model known as (temporal) coupled mode theory (CMT).…
Open geometry Fourier modal method: Modeling nanophotonic structures in infinite domains
Teppo Häyrynen, Jakob Rosenkrantz de Lasson, Niels Gregersen
We present an open geometry Fourier modal method based on a new combination of open boundary conditions and an efficient -space discretization. The open boundary of the computat…
Spectral symmetry of Fano resonances in a waveguide coupled to a microcavity
Andreas Dyhl Osterkryger, Jakob Rosenkrantz de Lasson, Mikkel Heuck +3
We investigate the parity of transmission spectra in a photonic crystal (PhC) waveguide with a side-coupled cavity and a partially blocking element. We demonstrate, by means of num…
Semi-analytical quasi-normal mode theory for the local density of states in coupled photonic crystal cavity-waveguide structures
Jakob Rosenkrantz de Lasson, Philip Trøst Kristensen, Jesper Mørk +1
We present and validate a semi-analytical quasi-normal mode (QNM) theory for the local density of states (LDOS) in coupled photonic crystal (PhC) cavity-waveguide structures. By me…
Impact of slow-light enhancement on optical propagation in active semiconductor photonic crystal waveguides
Yaohui Chen, Jakob Rosenkrantz de Lasson, Niels Gregersen +1
We derive and validate a set of coupled Bloch wave equations for analyzing the reflection and transmission properties of active semiconductor photonic crystal waveguides. In such d…
Calculation, normalization and perturbation of quasinormal modes in coupled cavity-waveguide systems
Philip Trøst Kristensen, Jakob Rosenkrantz de Lasson, Niels Gregersen
We show how one can use a non-local boundary condition, which is compatible with standard frequency domain methods, for numerical calculation of quasinormal modes in optical caviti…
A roundtrip matrix method for calculating the leaky resonant modes of open nanophotonic structures
Jakob Rosenkrantz de Lasson, Philip Trøst Kristensen, Jesper Mørk +1
We present a numerical method for calculating quasi-normal modes of open nanophotonic structures. The method is based on scattering matrices and a unity eigenvalue of the roundtrip…
Three-dimensional integral equation approach to light scattering, extinction cross sections, local density of states and quasinormal modes
Jakob Rosenkrantz de Lasson, Jesper Mørk, Philip Trøst Kristensen
We present a numerical formalism for solving the Lippmann-Schwinger equation for the electric field in three dimensions. The formalism may be applied to scatterers of different sha…
