The finger sizing of interdigitated Schottky-barrier Metal-Semiconductor-Metal Photodetectors (MSM-PD) is discussed in this paper. We observe that an MSM-PD geometry with fast response speed can be determined by solving a special form of optimization problem called posynomial programming, for which very efficient global optimization methods have been developed. Our method, therefore, yields completely automated finger sizing of MSM-PD, directly from specifications.
