Abstract—Crosstalk performance of monolithically integrated multiwavelength optical cross-connects (OXC's) depends strongly on their architecture. In this paper, a semiquantitative analysis of crosstalk in 11 different architectures is presented. Two archi-tectures are analyzed numerically in more. This paper discusses the current state of optical switches and cross connects in the field of MOEMS. It is observed that (Voltage Optical Attenuator)–MZI has low cross-channel interference and the proposed structure reaches its efficient behavior, showing an error rate of ~. Reliability issues are of profound importance in attempting to introduce photonics in a broader context in communications, e. for cross-connects, ATM switches etc. Bringing together the wisdom of optical technology researchers, this issue of Communications of HUAWEI RESEARCH focuses on long-distance optical transmission, short-distance optical interconnection, and optical access. It presents the latest research progress of core technologies — including.
