Abstract
An algorithm based on phase spectrum analysis is proposed that can be used to correct the timing distortion between the multiple parallel demultiplexed post-sampling pulse trains in wavelength demultiplexing analog-to-digital converters. The algorithm is theoretically presented and its operational principle is explained. The algorithm is then applied to two parallel demultiplexed post-sampling signals from a proof-of-principle system and fairly good results are obtained. This algorithm is potentially applicable in other opto-electronic hybrid systems where an interleaving and/or multiplexing mechanism is utilized, such as optical time-division multiplexing and optical clock division systems, photonic arbitrary waveform generators, and so on.
