Sculpting harmonic comb states in terahertz quantum cascade lasers by controlled engineering
Elisa Riccardi, M. Alejandro Justo Guerrero, Valentino Pistore +6
Optical frequency combs (FCs), that establish a rigid phase-coherent link between the microwave and optical domains of the electromagnetic spectrum, are emerging as a key high-prec…
Modeling of Fluctuations in Dynamical Optoelectronic Device Simulations within a Maxwell-Density Matrix Langevin Approach
Johannes Popp, Johannes Stowasser, Michael A. Schreiber +5
We present a full-wave Maxwell-density matrix simulation tool including c-number stochastic noise terms for the modeling of the spatiotemporal dynamics in active photonic devices,…
Backscattering-Induced Dissipative Solitons in Ring Quantum Cascade Lasers
Lukas Seitner, Johannes Popp, Ina Heckelmann +5
Ring quantum cascade lasers have recently gained considerable attention, showing ultrastable frequency comb and soliton operation, thus opening a way to integrated spectrometers in…
Ultrashort pulse generation from a graphene-coupled passively mode-locked terahertz laser
Elisa Riccardi, Valentino Pistore, Seonggil Kang +10
The generation of stable trains of ultra-short (fs-ps), terahertz (THz)-frequency radiation pulses, with large instantaneous intensities, is an underpinning requirement for the inv…
Reducing the reflection error of PML absorbing boundary conditions within a generalized Maxwell-Bloch framework
Johannes Popp, Lukas Seitner, Michael Haider +1
We demonstrate a full-wave numerical Maxwell-Bloch simulation tool including perfectly matched layer (PML) absorbing boundary conditions. To avoid detrimental reflection errors at…
