GeSn alloys are promising candidates for complementary metal-oxide- semiconductor-compatible, tunable lasers. Relaxation of residual compressive strain in epitaxial GeSn has recently shown promise in improving the lasing performance. However, the suspended device configuration that is thus far intr...
