Laser line shape and spectral density of frequency noise
TL;DR: In this article, the authors show that the spectral density of a single-mode laser light is characterized in the microwave range by a frequency noise which essentially includes a white part and a 1/f (flicker) part.

Polarization modulation dynamics of vertical-cavity surface-emitting lasers with an extended cavity
TL;DR: In this paper, the authors considered the dynamics of the polarization of light in a VCSEL, extended by means of a quarter-wavelength plate in an external cavity, using a recent model which includes the carriers' spin interaction.

Switching between polarized modes of a vertical-cavity surface-emitting laser by isotropic optical feedback
TL;DR: In this paper, it was shown that polarization of light in a vertical-cavity surface-emitting laser subjected to isotropic optical feedback can jump regularly back and forth between two orthogonal states when the injection current is increased.

TL;DR: Experimental evidence of antiphase dynamics in self-pulsing erbium-doped fiber lasers operating simultaneously at 1.536- and 1.55-microm wavelengths is presented.

Characteristics of a semiconductor laser coupled with a fiber Bragg grating with arbitrary amount of feedback
TL;DR: In this paper, the authors put the stress on the interplay between external and internal cavities when the feedback strength is increased and showed that for strong feedback, new stationary solutions that do not exist in the case of conventional feedback appear, while the ellipse, which usually contains the modes and so-called antimodes, collapse in the plane frequency gain.
