摘要
In this paper, we research the influence of two-photon absorption effect for optical pulse wavelength selective switch array. Because two-photon absorption effect can make the shape of optical pulse change, the relative extinction ratio will be seriously affected. As long as normalized input power is well controlled, the influence of two-photon absorption can be minimized and the relative extinction ratio will be not clearly changed. Then, the function of pulse wavelength selection is well realized. It is beneficial to actually guide to fabricate an optical pulse wavelength selective switch array.
