"In the QDSOAs-TS-MZI architecture, a pair of identical QD-SOAs are cascaded and separated by optical bandpass filters in each interferometric branch. The serially inserted DI, on the other hand, adds a phase difference to the direct and delayed copies of the incoming switched signal. This in turn further enhances the switching performance and speed of the formed logic gates"
