| Abstract: | The comprehensive theoretical analyses and experimental studies on semiconductor disk lasers are presented. The edge-emitting
photoluminescence spectrum which reflects the essential emission properties of quantum wells is theoretically modeled, and
the result is in good agreement with the experiment. The surface-emitting photoluminescence spectrum which carries the characteristics
of the semiconductor microcavity is explained using the numerically simulated longitudinal confinement factor. The output
characteristic is modeled by taking into account the thermal effect, and the result is consistent with the experiment. The
oscillating mode of the laser is codetermined by the reflectivity of DBR, the edge-emitting, and the surface-emitting PL spectrum. |
