The design of semiconductor-based unstable resonators with laterally finite mirrors is investigated. A time-independent model used for tapered cavity semiconductor lasers is implemented to analyze this cavity design. Initial investigations show a significant improvement in external quantum efficiency, as well as a decrease in threshold current density as compared to the traditional tapered lasers with laterally infinite mirrors. The advantages and disadvantages of the proposed design will be discussed.
