Nanobeam Laser Cavities with High Quality-factor and Near-Unity Outcoupling Efficiency
Mathias Marchal, Meng Xiong, Evangelos Dimopoulos +3
Cavities with high quality (Q) factor and small mode-volume are crucial to realize high-performance nanolasers suitable for optical interconnects. In this work, we propose a novel…
Instantaneous modes in dispersive laser cavities
Kristian Seegert, Yi Yu, Mikkel Heuck +1
We develop a unified instantaneous-mode description for lasers with dispersive cavities, exploiting the separation of timescales between fast cavity fields and slow carrier dynamic…
A deterministic approach for integrating an emitter in a nanocavity with subwavelength light confinement
Valdemar Bille-Lauridsen, Rasmus Ellebæk Christiansen, Yi Yu +1
We introduce a novel light-matter interface that integrates a nanoscale buried heterostructure emitter into a dielectric bowtie cavity, co-localising the optical hotspot and the el…
Carrier Transport in Electrically-Driven Photonic Crystal Membrane Lasers
Mathias Marchal, Evangelos Dimopoulos, Kasper Spiegelhauer +5
We model carrier transport in photonic crystal lasers with lateral current injection through two-dimensional (2D) finite-volume simulations. Though such lasers can achieve ultra-lo…
Enhancement and speed-up of carrier dynamics in a dielectric nanocavity with deep sub-wavelength confinement
Gaoneng Dong, Ali Nawaz Babar, Rasmus Ellebæk Christiansen +4
The emergence of dielectric bowtie cavities enable optical confinement with ultrahigh quality factor and ultra-small optical mode volumes with perspectives for enhanced light-matte…
A nanolaser with extreme dielectric confinement
Meng Xiong, Yi Yu, Yury Berdnikov +5
The interaction between light and matter can be enhanced by spatially concentrating the light field to boost the photon energy density and increasing the photon dwell time to prolo…
Self-pulsing dynamics in microscopic lasers with dispersive mirrors
Kristian Seegert, Mikkel Heuck, Yi Yu +1
We show that a passive dispersive reflector integrated into a semiconductor laser can be used to tailor the laser dynamics for the generation of ultrashort pulses as well as stable…
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…
