Letting go with lasers
Letting go lasers
2015/7/13
Small objects tend to cling to everything. It's why parents dread hosting parties that involve confetti. It's why glitter is fun for crafts--until it finds its way onto everything else you touch.When ...
Highly Tm-doped silicate glasses and fibers were developed, which exhibit a high slope efficiency of 68.3% and a gain per unit length of greater than 2dB/cm. Single frequency fiber lasers with laser l...

The investigation of the nonlinear dynamics of a semiconductor laser based on nonlinear optical loop mirror (NOLM) feedback using Ge doped optical fiber was carried out experimentally. Animations of c...
Taming random lasers through active spatial control of the pump
Taming random lasers active spatial control pump
2012/2/24
Active control of the pump spatial profile is proposed to exercise control over random laser emission. We demonstrate numerically the selection of any desired lasing mode from the emission spectrum. A...
On the Interest of Chirped Lasers for AMOOFDM Transmissions in Long Distance PON Networks
Fiber optics communications Modulation
2015/5/26
We report the performance of a chirped laser in IMDD-based transmissions and we show that the interplay between laser chirp and fiber dispersion can be very attractive for long distance PONs if adapti...
