TL;DR: In this article, a model based on a mean field approach for the two counter-propagating modes is proposed to study the semiconductor ring laser dynamics, and the authors obtain good numerical agreement between experiment and theory, and also an estimation for the otherwise unknown scattering parameters.

TL;DR: A bifurcation from bidirectional stable operation to a regime with alternate oscillations of the counterpropagating modes was observed experimentally and is theoretically explained through a two-mode model.

TL;DR: In this article, the linear autocorrelation and cross correlation properties of the two counter-propagating modes of a monolithic semiconductor ring laser (SRL) are investigated in a bidirectional regime where the two modes are active at the same time and have equal power.

TL;DR: In this article, the authors report on a reliable and low-cost descriptor method for high-bandwidthphotodiodes using the photomixing technique, they were able to experimentally characterize the electrical response of commercialdevices up to 60GHz using both DFB and low cost Fabry-Perot laser.

TL;DR: In this paper, the authors demonstrate that the normal photomixing scheme, i.e., one built around a two-mode laser (or a mode-locked laser) as the source, and a fast photodiode acting as the optical mixer of the two modes, can be used also to perform electrical demodulation of an incoming weak signal at the same frequency.
