Publication number: 20200412447Abstract: An optical performance monitor comprises a first stage configured to receive a multiplexed optical signal. The first stage is tunable over a period. The first stage periodically filters the multiplexed optical signal over an optical channel to produce a fine filtered optical signal. A second stage is coupled to the first stage and has a second-stage transfer function. The second stage receives the fine filtered optical signal and produces one or a plurality of interfered optical signal pairs. A third stage is coupled to the second stage and has a third-stage transfer function. The third stage receives the optical signal pairs and demultiplexes the optical signal pairs to produce a plurality of demultiplexed optical signals. The combination of the second-stage transfer function and the third-stage transfer function is flatter over the optical channel than the third-stage transfer function.Type: ApplicationFiled: June 1, 2020Publication date: December 31, 2020Applicants: Huawei Technologies Canada Co., Ltd., The University of OttawaInventors: Mohammad Mehdi MANSOURI RAD, Patrick DUMAIS, Trevor James HALL, Mehedi HASAN
