A theoretical framework based on the eight-band k.p formalism and the envelope function approximation (EFA) formalism is developed to investigate the luminescence properties of GeSn alloys. Using this framework, the steady-state radiative carrier lifetimes of Ge0.83 Sn0.17 samples are estimated in the ns order over the 4–80 K temperature range.

We report on the combination of a high-field terahertz source and two-dimensional near-field imaging capability using SrTiO3 (STO) crystal. Specifically, we show that the surface of STO allows sub-picosecond Kerr-effect switching and multi-ps THz intensity recording. The sensitivity and spatial resolution achieved by the STO sensor outperform current near-field THz sensors based on the Pockel effect, and more importantly, its ability to remain polarized for several picoseconds may open the door to a new strategy for building an ultrafast two-dimensional space-time THz memory.

This paper reviews the opportunities and challenges of UWB transmission systems in terms of ISRS and fibre attenuation. We also discuss a novel design of UWB dual-stage discrete Raman amplifier spanning E-to- L bands and numerically demonstrate the gain, noise figure and output power performances.

Information rates of C-band Nyquist-spaced optical fiber communication systems with erbium-doped fiber amplifier (EDFA) and distributed Raman amplification (DRA) schemes were discussed. Results indicate that the nonlinearity compensation performance depends on transmission distances and modulation formats.
