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…
Transformation-optics modeling of 3D-printed freeform waveguides
Aleksandar Nesic, Matthias Blaicher, Emilio Orlandini +10
Multi-photon lithography allows to complement planar photonic integrated circuits (PIC) by in-situ 3D-printed freeform waveguide structures. However, design and optimization of suc…
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…
Photon-driven broadband emission and RF injection locking of THz quantum cascade laser frequency combs
Andres Forrer, Martin Franckié, David Stark +4
We present homogeneous quantum cascade lasers (QCLs) emitting around 3 THz which display bandwidths up to 950 GHz with a single stable beatnote. Devices are spontaneously operating…
