Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We demonstrate the first all-chalcogenide ring fiber laser as well as the first all chalcogenide Brillouin fiber laser. The compact device is made from the combination of an As2Se3 optical fiber coupler for the insertion of pump light and extraction of laser light, as well as an As2S3 nonlinear gain fiber to ensure laser oscillation. Thanks to the strong Brillouin gain of As2S3, only 3m of amplifying fiber is required to reach laser threshold, thus making a resonant cavity with a free spectral range significantly larger than the Brillouin gain spectrum. The laser therefore naturally enables single longitudinal mode operation without additional filtering device. Acting as a coherence enhancing component, the resulting proof of concept Brillouin laser benefits of a linewidth reduction factor of 7 with respect to the pump laser.
