Tunable transform-limited pulse generation using self-injection locking of an FP laser
TLDR
In this paper, a Fabry-Perot laser diode coupled to a fiber loop containing a fiber FabryPerot resonator (FFPR) and a polarization controller was used to generate near transform-limited pulses.Abstract:
Wavelength-tunable, near transform-limited pulses have been generated using a Fabry-Perot laser diode coupled to a fiber loop containing a fiber Fabry-Perot resonator (FFPR) and a polarization controller. The ratio of transmitted to reflected light from the loop can be adjusted using the polarization controller. Single-mode operation of the gain-switched laser is achieved by self-injection locking, which is induced by light reflected from the fiber loop. The resulting output pulse has a time-bandwidth product of 0.4 and is tunable over about 15 nm by varying the tuning voltage of the FFPR. >read more

Jitter and dynamics of self-seeded Fabry-Perot laser diodes
TL;DR: In this article, the authors investigated the time jitter and the switch-on dynamics of self-seeded gain-switched Fabry-Perot semiconductor lasers and showed that self-seeding leads to single-mode emission and is shown to reduce the turn-on delay to 210 fs, which is one order of magnitude lower than observed for gainswitched DFB-lasers.

Fiber loop reflectors
TL;DR: In this article, the theory and application of fiber loop reflectors, fabricated by forming a fiber loop between the output ports of a directional coupler, is described, and the reflectivity of the loop is shown to depend upon the coupling characteristics of the coupler and on the degree of birefringence in the fiber loop.

TL;DR: In this paper, it was shown that solitons of different velocities are transparent to each other in a system using lumped amplifiers, as long as the length of the collision is long enough relative to the spacing between amplifiers or a possibly longer period of variation in some other parameter, such as the fiber's chromatic dispersion.

TL;DR: Under certain conditions, birefringence leads to polarization sensitivity in the nonlinear regime, which is likely to be contributing to instabilities that have been observed recently in mode-locked fiber lasers.
