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…
Continuously tunable coherent pulse generation in semiconductor lasers
Urban Senica, Michael A. Schreiber, Paolo Micheletti +4
In a laser, the control of its spectral emission depends on the physical dimensions of the optical resonator, limiting it to a set of discrete cavity modes at specific frequencies.…
