TL;DR: In this article, the authors identify the problems commonly encountered, including poor accuracy of the avalanche generation description, numerically induced pseudodiffusion, modeling of unsaturated velocity and negative mobility carrier dynamics, field reversal, and the treatment of the diode-load interaction, and describe numerical methods developed to overcome them.

TL;DR: In this article, the output of a GaAlAs laser, modulated at 2.6 GHz, was used to optically sub-harmonic injection lock a 7.8 GHz Impatt oscillator.

TL;DR: In this paper, a series of AlxGa(1−x)As were grown by molecular beam epitaxy (MBE) at the technologically relevant composition range, x < 0.45, and characterized using spectroscopic ellipsometry to provide accurate refractive index values in the wavelength region below the bandgap.

TL;DR: In this article, the first theoretical analysis and experimental realization of an optical frequency modulation coherent detection (FMCD) link working at microwave frequencies is reported, and a detailed theoretical analysis of the SNR of FMCD links is carried out and compared to that for IMDD links.

TL;DR: In this article, the integrated subwavelength aperture probe designed for THz near-field scanning probe microscopy can be used to map surface plasmon waves at THz frequencies.
