Ultra-Low-Temperature Silicon and Germanium-on-Silicon Avalanche Photodiodes

Mahdi Aminian

In this thesis we propose the use of photodiodes fabricated in planar technologies to address the detection problem in these applications. A number of solutions exist, optimized for these wavelengths, based on Germanium (Ge) and other III-V materials. In t ...

A 270×1 Ge-on-Si photodetector array for sensitive infrared imaging

Edoardo Charbon, Mahdi Aminian, Lin Qi

A CMOS compatible Ge photodetector (Ge-PD) fabricated on Si substrates has been shown to be suitable for near infrared (NIR) sensing; linear and avalanche detection, in both proportional and Geiger modes have been demonstrated, for photon counting at room ...

InGaN alloys and heterostructures

Marlene Glauser

The III-nitride semiconductor material system - (InAlGa)N - is of highest interest for optoelectronic applications due to its direct bandgap, tunable from the ultraviolet to the infrared spectral range. The most well-known are white light-emitting diodes, ...

Single-Photon Avalanche Diode Imagers Applied to Near-Infrared Imaging

Edoardo Charbon, Juan Mata Pavia, Martin Wolf

Single-photon avalanche diodes (SPADs) can be integrated into large pixel arrays. The aim of this paper is to present a view on how these imagers change the paradigm of wide-field near-infrared imaging (NIRI). Thanks to the large number of pixels that they ...

A review of MBE grown 0D, 1D and 2D quantum structures in a nanowire

Anna Fontcuberta i Morral, Xin Zhou, Silvija Gradecak

We review different strategies to achieve a three-dimensional energy bandgap modulation in a nanowire (NW) by the introduction of self-assembled 0D, 1D and 2D quantum structures, quantum dots (QDs), quantum wires (QWRs) and quantum wells (QWs). Starting wi ...

Photocurrent spectroscopy of site-controlled pyramidal quantum dots

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Jérôme Faist, Arun Mohan

Intraband photocurrent spectroscopy of site-controlled pyramidal quantum dots by inserting them into the intrinsic region of n-i-n like quantum dot infrared photodetector structure is reported. The photovoltaic response is observed in the mid-infrared regi ...

Tunable and Broadband Nanostructured Photonic Devices

Pierre-Yves Baroni

The main topic of this thesis is the fabrication and characterization of structures smaller than the wavelength of light, for operation in the visible or near infrared spectral range. In the first part of this thesis, the fabrication of periodic structures ...

Couches minces nanoporeuses pour la réalisation de dispositifs optiques

Gaëtan Wicht

The physical-chemical properties of polymer films can be modified by embedding inorganic materials (e. g. inorganic nanoparticles) into the polymer matrix. Depending both on the material properties (e. g. nanoparticles concentration) and on the fabrication ...

Micromirrors for integrated tunable mid-infrared detectors and emitters

Niels Quack

The mid-infrared range is of interest in spectroscopic applications, due to the large number of organic compounds that exhibit characteristic absorption bands in this spectral region. Semiconductor technology, however, has been developed mainly for the nea ...
