Figure 2 | Improved laser performances by GeSnOI platform

Caption

Laser performances with GeSnOI disk resonators as compared with those of conventional as-grown GeSn disks. (a) Light in-Light out curves. (b) Laser thresholds as a function of the disk diameter. (c) Maximum lasing temperature as a function of the disk diameter. Smaller disk diamter were not reachable with the as-grown GeSn layers because of their undercut.
