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

Michele Tamagnone

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 ...

A Low-Noise CMOS THz Imager Based on Source Modulation and an In-Pixel High-Q Passive Switched-Capacitor N-Path Filter

Christian Enz, Assim Boukhayma

This paper presents the first low noise complementary metal oxide semiconductor (CMOS) terahertz (THz) imager based on source modulation and in-pixel high-Q filtering. The 31 × 31 focal plane array has been fully integrated in a 0 . 13 μ m standard CMOS pr ...

Low frequency terahertz-induced demagnetization in ferromagnetic nickel

Christoph Peter Hauri, Mostafa Shalaby

A laser stimulus at terahertz (THz) frequency is expected to offer superior control over magnetization dynamics compared to an optical pulse, where ultrafast demagnetization is mediated by heat deposition. As a THz field cycle occurs on a timescale similar ...

2D Material-Based Bolometer

Tom Larsen, Marco Di Gisi

Measurement of thermal radiation through uncooled bolometers is at the heart of many industrial applications. From the development of the Honey- well silicon microstructure developed in 1982, no particular change in paradigm was recorded. The advent of 2D- ...

Dielectric Resonator Reflectarray as High-Efficiency Nonuniform Terahertz Metasurface

Julien Perruisseau-Carrier

Advances in terahertz technology rely on the combination of novel materials and designs. As new devices are demonstrated to address the terahertz gap, the ability to perform high-efficiency beam control will be integral to making terahertz radiation a prac ...

Review of amorphous silicon based particle detectors: the quest for single particle detection

Christophe Ballif

Hydrogenated amorphous silicon (a-Si:H) is attractive for radiation detectors because of its radiation resistance and processability over large areas with mature Si microfabrication techniques. While the use of a-Si:H for medical imaging has been very succ ...

Institute of Physics2016

We present giant cross phase modulation of a 60 fs nIR pulse in GaP by means of an intense Terahertz transient. The THz field induces up to 500% spectral broadening supporting sub-10 fs nIR pulses. ...

High-performing nonlinear visualization of terahertz radiation on a silicon charge-coupled device

Christoph Peter Hauri, Mostafa Shalaby

Photoinduced electron transitions can lead to significant changes of the macroscopic electronic properties in semiconductors. This principle is responsible for the detection of light with charge-coupled devices. Their spectral sensitivity is limited by the ...

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 ...

Spectrally intense terahertz source based on triangular Selenium

Christoph Peter Hauri, Mostafa Shalaby

The intensity of a nonlinear terahertz (THz) source is primarily given by its spectral density. In this letter, we introduce triangular Selinium (Se) as a novel THz emitter and show numerically its superior properties to the currently used crystals for int ...
