H. Ohta et al., Measurement of 200Gbit/s optical eye diagram by optical sampling with gain-switched optical pulse, ELECTR LETT, 36(8), 2000, pp. 737-739
A 200Gbit/s optical eye diagram, which was generated by compressing and fou
r-multiplexing a 10Gbit/s optical signal, has been clearly observed by usin
g an optical sampling system. The time resolution was 1.25ps and the timing
jitter was 160fs with a timing-jitter reduced gain-switched optical pulse,
and the 3dB bandwidth of the optical frequency was 310GHz.
