K. Kikuchi et K. Matsuura, TRANSMISSION OF 2-PS OPTICAL PULSES AT 1550 NM OVER 40-KM STANDARD FIBER USING MIDSPAN OPTICAL-PHASE CONJUGATION IN SEMICONDUCTOR OPTICAL AMPLIFIERS, IEEE photonics technology letters, 10(10), 1998, pp. 1410-1412
We demonstrate transmission of 2-ps optical pulses at 1550 nm over 40
km of standard fiber by employing midspan optical phase conjugation in
semiconductor optical amplifiers (SOA's). The second order group-velo
city dispersion of the fiber is completely compensated and the third-o
rder dispersion becomes a major transmission limitation. This experime
nt shows that the midspan optical phase conjugation system using SOA's
is applicable to ultrahigh bit rates greater than 100 Gb/s.
