Threshold behavior in spin lasers: Spontaneous emission and nonlinear gain
Threshold behavior in spin lasers: Spontaneous emission and nonlinear gain
A hallmark of spin-lasers, injected with spin-polarized carriers, is their threshold behavior with the onset of stimulated emission. Unlike the single threshold in conventional lasers with unpolarized carriers, two thresholds are expected in spin lasers. With the progress in scaled-down lasers and the use of novel two-dimensional materials it is …
