Optical frequency comb (OFC) emission in quantum cascade lasers (QCLs) is highly attractive for applications in metrology and sensing. Recently, coherent OFC mode-locking with large intermodal spacing was demonstrated in QCLs. These self-starting har

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, such as quantum cascade lasers and quantum dot structures. The coheren

Compared to state-of-the-art IGBTs, SiC power semiconductors allow to achieve ever higher system efficiencies and higher power densities in next-generation Variable Speed Drives (VSDs), thanks to their smaller relative chip size, ohmic on-state chara

This paper investigates the Electromagnetic Interference (EMI) noise signature of three-phase three-level (3L) Triangular Current Mode (TCM)-modulated grid-tied Photovoltaic (PV) inverters that achieve full Zero Voltage Switching (ZVS) and thus minim

Next-generationVariable Speed Drive (VSD) systems utilize SiC MOSFETs to achieve both high efficiency through reduced bridge-leg losses and high power density through an order-of-magnitude increase in switching frequency or reduction of the DC-link c

Triangular-current-mode (TCM) modulation guarantees zero-voltage-switching across the mains cycle in AC-DC power converters, eliminating hard-switching with a minor ${\approx} {30}{\%}$ penalty in conduction losses over the conventional continuous cu

For three-phase AC-DC power conversion, the widely-used continuous current mode (CCM) modulation scheme results in relatively high semiconductor losses from hard-switching each device during half of the mains cycle. Triangular current mode (TCM) modu
