Abstract

Optical buffer is an important component in optical switching and optical signal processing. In this paper, we present a novel all-optical buffer based on nonlinear polarization rotation induced by injection current of semiconductor optical amplifier. With Mueller matrix, we theoretically investigate the change of polarization state induced by nonlinear polarization rotation in semiconductor optical amplifier. The operation of the proposed optical buffer at 2.5Gb/s is experimentally setup. The loading and reading operations with 1024bit with this optical buffer are demonstrated. Polarization maintenance is taken into account to give the optimum operation condition
