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.

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.

We review recent advances of InGaAs-channel grating-gate high-electron-mobility transistors as fast, highly sensitive, room-temperature-operating THz detectors for THz wireless communication systems and THz imaging/sensing systems. We experimentally demonstrated that the gate-readout of the photovoltage from a detector, instead of the conventional drain-readout, simultaneously enables the scaling of the photovoltage with the active area size, the impedance matching with 50-Ω interconnection systems, and enhancement of the responsivity owning to the “3D rectification effect”.
