ROGUE-based, random distributed feedback lasers (Conference Presentation)

In this work, we show that the enhanced backscatter originating from the recently discovered ROGUE (Random Optical Grating by Ultraviolet or ultrafast laser Exposure) increases the performance of random distributed feedback lasers. The inscription of ROGUEs inside regular optical fibers leads to lower power thresholds, and more compact lasers requiring shorter lengths to achieve lasing. These ROGUEs can also be used in half-open cavities, to further decrease the lasing threshold.
