随着超高速光纤通信的发展，需要一种能够实现超大数据吞吐量交换的空分光交换网络。在大规模设计这种网络时，半导体光行波放大器(Twas)被用来降低光开关损耗[1]。在大规模的光交换网络中，通过单片集成行波管获得的无损半导体光开关是最理想的方法，因为它可以很小，并且可以在不担心损耗预算的情况下扩大网络。光子交换网络越大，低串扰就越重要，因为累积串扰随着开关矩阵的放大而增加[2]。
According to the progresses of ultra-high bit rate optical fiber communication, a space division photonic switching network is desired to realize ultra-large data throughput switching. In designing such a network on a large scale, semiconductor optical traveling-wave amplifiers (TWAs) have been used to reduce optical switch loss[1]. A lossless semiconductor optical switch attained by monolithically integrating a TWA is the most desirable approach for large scale photonic switching networks, because it can be small and enable the network to be enlarged without worrying about loss budget. The larger the photonic switching network, the more important low crosstalk is, since the accumulated crosstalk increase with magnification of the switch matrix[2].
