Optimal operating conditions and modulation format for 160 Gb/s signals in a fiber parametric amplifier used as a slow-light delay line element

Abstract

We study optimal operating conditions for 160-Gb/s signals traversing a slow-light delay line based on parametric amplification. Six phase modulated formats are investigated, including CSRZ, PAP-CSRZ, GAP-CSRZ, RZ duobinary, RZ DPSK and RZ.

Performance of a silicon-microring slow-light delay line for advanced modulation formats

“…Some on-chip delay lines based on silicon waveguide have been demonstrated including cascaded micro-ring resonator based all-pass filters (APF) configuration, and coupled resonator optical waveguides (CROW) configuration [1]. On the other side, significant progress has been made in the advanced modulation formats [2] for the state-of-the-art communication systems to provide superior performances and meet diverse requirements. However, to the best of our knowledge, no thorough experimental studies have been carried out on the performances of various formats through silicon based slow-light devices.…”
