Effects of optical nonlinearity in picosecond optical pulse transmission over 200 km of optical fibers using a midspan optical phase conjugation

Abstract

In this report, we experimentally demonstrate that mid-span optical phase conjugation(OPC) transmissions have large tolerance for the nonlinearity. We also compare the results with that in the transmission experiments using 200 km large-core SMFs and NDFs. We used a semiconductor optical amplifier (SOA) as an optical phase conjugator and 200 km of standard SMFs as a transmission line. We found that mid-span OPC has large tolerance for optical nonlinearity in the transmission line.
