Abstract

In this work, device designs to improve the power conversion efficiency of PCSELs are analyzed by a probabilistic Markov chain model. Critical comparison of total parasitic loss, output ratio, threshold current and power conversion efficiency at 1 W are considered. This is carried out for a range of possible new device designs that address self-absorption in the boundary PC to the PCSEL active element.
