Ultrabroadband Gain-Switched and Superluminescent Terahertz Semiconductor Lasers
Urban Senica, Michael A. Schreiber, Mattias Beck +3
Terahertz quantum cascade lasers (THz QCLs) are chip-scale semiconductor lasers operating in the frequency range between 1-6 THz, useful as compact sources for spectroscopy, commun…
Short period InGaAs/AlInAs THz quantum cascade laser in thin double metal cavities operating up to 188K
Sebastian Gloor, David Stark, Martin Frankié +4
We present a two-well terahertz (THz) quantum cascade laser designed for high temperature operation based on the InGaAs/AlInAs material system. The lighter effective mass and highe…
Short mode-locked pulses from planarized Y-coupled THz lasers
Urban Senica, Tabea Bühler, Sara Cibella +4
Short THz pulses are highly attractive both for fundamental research and practical applications in this underdeveloped region of the electromagnetic spectrum. Typically, THz pulses…
On-chip, inverse-designed active wavelength division multiplexer at THz frequencies
Valerio Digiorgio, Urban Senica, Paolo Micheletti +3
The development of photonic integrated components for terahertz has become an active and growing research field. Despite its numerous applications, several challenges are still pre…
