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…
