lasers as the degree of freedom to realize manipulation of mode quality (Q) factor and lasing …

A novel approach using a dual-mode square microlaser as the pump source is
demonstrated to produce wideband optical frequency comb (OFC). The enhanced nonlinear …

Low relative intensity noise (RIN) was demonstrated experimentally for hybrid square-
rectangular lasers (HSRLs). In this paper, RIN of the HSRL is numerically simulated and the …

Broad-area semiconductor lasers are employed in many high-power applications, however,
their spatio-temporal dynamics is complex and intrinsically unstable due to the interaction of …
