Pulse Generation by On‐Chip Dispersion Compensation at 8 µm Wavelength
Laser &Photonics Reviews, EarlyView.This work demonstrates on‐chip pulse generation at 8 μm$\mathrm{\mu}\mathrm{m}$ using chirped Bragg gratings in SiGe graded‐index photonic circuits to compensate the quadratic phase of quantum cascade laser frequency combs. With this approach pulses as short as 1.39 ps were produced, close to the transform limit, representing a key step toward compact,

physica status solidi (RRL) – Rapid Research Letters, EarlyView.A new parameterization of Si and Ge in the framework of the extended Hückel theory is presented. Bandgap and effective mass are calculated for unstrained and biaxially strained SiGe alloys. In SiGeC alloys with C atoms in close proximity, additional bands are observed, which are related to defect states in real crystals.

Small Methods, EarlyView.Four‐dimensional scanning transmission electron microscopy (4D‐STEM) is used to acquire multiple convergent beam electron diffraction (CBED) patterns around focused ion beam (FIB) dwelled spots. Peak signal‐to‐noise ratio (PSNR) analysis, following calibration with well‐known implantation dose squares, enables full quantification of the FIB profile ...

Substrate orientation and alloy composition effects in n-type SiGe quantum cascade structures [PDF]
, 2008 We show using a theoretical self-consistent effective mass/rate equation approach that n-type SiGe-based quantum cascade lasers are potentially made viable by either using the (111) orientation or a Ge-rich ...
