Dynamically reconfigurable THz quantum walk comb laser through subharmonic excitation
Valerio Digiorgio, Robert Matthew Gray, Marco Raffa +5
On-chip frequency combs are increasingly relevant to both laser science and applications. Broad bandwidths and flat-top spectral envelopes are especially desirable for precision sp…
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.…
Broadband surface-emitting THz laser frequency combs with inverse-designed integrated reflectors
Urban Senica, Sebastian Gloor, Paolo Micheletti +4
THz quantum cascade lasers (QCLs) based on double metal waveguides feature broadband and high-temperature devices for use in spectroscopy and sensing. However, their extreme field…
THz optical solitons from dispersion-compensated antenna-coupled planarized ring quantum cascade lasers
Paolo Micheletti, Urban Senica, Andres Forrer +6
Quantum Cascade Lasers (QCL) constitute an intriguing opportunity for the production of on-chip optical Dissipative Kerr Solitons (DKS): self-organized optical waves which can trav…
Planarized THz quantum cascade lasers for broadband coherent photonics
Urban Senica, Andres Forrer, Tudor Olariu +6
Recently, there has been a growing interest in integrated THz photonics for various applications in communications, spectroscopy and sensing. We present a new integrated photonic p…
Regenerative Terahertz Quantum Detectors
Paolo Micheletti, Jerome Faist, Tudor Olariu +3
Because of the ultrafast and photon-driven nature of the transport in their active region, we demonstrate that quantum cascade lasers can be operated as resonantly amplified terahe…
