No ooIf -qt -S-1 8S,7Abstract Semiconductor optical amplifiers (SOAs) can be used in space-division (SD) switches to provide both switching and optical gain. We present a general analysis of optical switches using SOAs, considering noise and saturation effects associated with amplified spontaneous emission. Based on this analysis, we derive size limitations of SD switches.Three specific SD switching architectures are considered. For a the lumped gain matrixvector multiplier (MVM) switch, switch sizes are limited to the range of 3000x3000 for SOAs with saturation output powers of 100 mW. Based on the effects considered in our analysis, distributed gain MVM switches and Benes switches are not limited by signal-tonoise ratio and saturation up to sizes of 10 8°x 10 80 for SOAs with saturation output powers of 100 mW. r-, ..

“…Optical amplifiers can be used to overcome these losses [ 1]. In SD switches, semiconductor optical amplifiers (SOAs) have the advantage over erbium-doped fiber amplifiers that they can be switched quickly, are smaller, and are amenable to monolithic integration with passive waveguiding structures and electronics.…”
