Optically pumped low-threshold microdisk lasers on a GeSn-on-insulator substrate with reduced defect density

Optically pumped low-threshold microdisk lasers on a GeSn-on-insulator substrate with reduced defect density

Despite the recent success of GeSn infrared lasers, the high lasing threshold currently limits their integration into practical applications. While structural defects in epitaxial GeSn layers have been identified as one of the major bottlenecks towards low-threshold GeSn lasers, the effect of defect...
