Theory, design and measurement of near-optimal graphene reconfigurable and non-reciprocal devices at terahertz frequencies

This thesis explores the applications of graphene for terahertz and far infrared optical components and antennas, with particular emphasis on tunable and non-reciprocal devices. Both terahertz technologies and graphene are emerging fields which hold many p ...

Intense, carrier frequency and bandwidth tunable quasi single-cycle pulses from an organic emitter covering the Terahertz frequency gap

Christoph Peter Hauri

In Terahertz (THz) science, one of the long-standing challenges has been the formation of spectrally dense, single-cycle pulses with tunable duration and spectrum across the frequency range of 0.1–15 THz (THz gap). This frequency band, lying between the el ...

Temporal and spectral shaping of broadband terahertz pulses in a photoexcited semiconductor

Christoph Peter Hauri, Mostafa Shalaby

Transmission through a photoexcited semiconductor is used to temporally and spectrally shape a terahertz (THz) pulse. By adjusting the optical pump-THz probe delay, we experimentally introduce a polar asymmetry in the pulse profile as large as 92%. To shap ...

Terahertz passive components for Dynamic Nuclear Polarization Nuclear Magnetic Resonance applications

Emile Jacques de Rijk

Terahertz radiation, THz = 1012 Hz, refers to electromagnetic signals with frequencies in the range of 0.3 to 3 THz, and wavelengths between 1 and 0.1 mm. This part of the electromagnetic spectrum is located in between millimeter waves at lower frequencies ...

Low-rank Matrix Approximation Using Point-wise Operators

Arash Amini, Amin Karbasi

Extracting low dimensional structure from high dimensional data arises in many applications such as machine learning, statistical pattern recognition, wireless sensor networks, and data compression. If the data is restricted to a lower dimensional subspace ...

Note: Stacked rings for terahertz wave-guiding

Stefano Alberti, Jean-Philippe Ansermet, Jean-Philippe Hogge, Emile Jacques de Rijk, Alessandro Macor

We demonstrate the construction of corrugated waveguides using stacked rings to propagate terahertz frequencies. The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the HE11 mode. This simple concept opens the way for ...
