We present a surface textured Si SPAD with improved detection efficiency and without sacrificing dark count rate or jitter distribution. Texturing reduces reflection, allows weak light trapping and is CMOS and lithography compatible.

Highly tensile-strained Ge/SiGe MQW structures on Si substrates are formed by introducing micro-bridge structures. Lattice matching and strain of epitaxial structures are analyzed by XRD. Large strain induced by micro-bridges is confirmed with Raman

We demonstrate, for the first time, the photoluminescence from suspended Ge/SiGe quantum-well microdisks. The optical mode resonances of the photoluminescence spectra are associated with Fabry-Perot modes and whispering gallery modes.

Although the development of a monolithically-integrated, silicon-compatible light source has been traditionally limited by the indirect band gaps of Group IV materials, germanium-tin (Ge 1-x Sn x ) is predicted to exhibit direct band gap behavior. In

In this paper, a novel electro-absorption modulation mechanism based on coupled-quantum-wells (CQWs) is proposed and demonstrated. Compared to a quantum-confined-stark-effect (QCSE) modulator with multiple fully decoupled single-QWs, the newly design

Unstrained Ge1−xSnx layers of various Sn concentration (1.5%, 3%, 6% Sn) and Ge0.97Sn0.03 layers with built-in compressive (e = −0.5%) and tensile (e = 0.3%) strain are grown by molecular beam epitaxy and studied by electromodulation spectroscopy

The development of a precise micromachining process for Ge1–xSnx has the potential to enable both the fabrication and optimization of Ge1−xSnx-based devices in photonics and microelectromechanical systems. We demonstrate a digital etching scheme

Perceptions of Medieval Manuscripts takes as its starting point an understanding that a medieval book is a whole object at every point of its long history. As such, medieval books can be studied most profitably in a holistic manner as objects-in-the-
