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…
Amplitude- and frequency-modulated combs from an actively locked metasurface external-cavity laser
Marco Raffa, Jordane Bloomfield, Yu Wu +5
The paper demonstrates a THz metasurface VECSEL that can be actively switched between amplitude-modulated (mode-locked) pulses and frequency-modulated quantum-walk comb states usin…
Profiling THz Beams With Off-Label Use of Infrared Microbolometric Cameras
Gabriel Nagamine, Carlo Vicario, Tariq Leinen +6
Visualizing the spatial profile of light beams is essential for evaluating irradiance, characterizing beam quality, and achieving precise alignment. In the optical spectral range,…
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…
Spectral shaping of fast-gain frequency combs through phases in synthetic dimensions
Diego Piciocchi, Alexander Dikopoltsev, Ina Heckelmann +3
Optical frequency comb devices have unlocked new capabilities in telecommunications, sensing, and metrology. Yet, precise in situ control of the comb spectral envelope remains extr…
Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. RakiÄ, Dragan Indjin +46
Quantum cascade lasers (QCLs) are unipolar semiconductor lasers first demonstrated in 1994. Since then, they have played a central role in advancing mid-infrared and terahertz phot…
