Using Signal Pre-Distortion to Enhance the Performance of All-Optical Clock Recovery

摘要

We investigate a clock enhancement technique using semiconductor optical amplifier based Mach-Zehnder interferometer (SOA-MZI) for all-optical clock recovery with numerical simulations. The simulations determine the optimal operation points of the SOA-MZI for return-to-zero (RZ) and non-return-to-zero (NRZ) inputs, achieving effective clock performance improvement.
