Abstract

Among the various types of semiconductor injection lasers, there is the transverse junction strip (TJS) laser. A major problem in the functioning of the TJS laser is that the leakage current, which does not contribute to laser operation, increases with increasing current density. The rapid increase in threshold current produces a rise in temperature until laser oscillation has ceased due to the heat generated in the device. As a result, the output power of these lasers has been greatly limited, as compared to other types of injection lasers, and is accompanied with facet or catastrophic damage.
