Abstract

PURPOSE:To widen effective gain band width and to amplifier signal light excellently by using light which contains plural frequency components with narrower frequency intervals of the Brillouin gain band width of an optical fiber as exciting light. CONSTITUTION:The exciting light of this method has frequency components shown in a figure and their frequency intervals are about 70MHz and narrower than 100MHz as the Brillouin gain band width. Consequently, signal light of 100Mb/s can be amplified in this case almost without any waveform distortion. When a semiconductor laser which oscillates in single longitudinal mode like before is used as an exciting light source and the signal light of 100Mb/s is amplified for comparison with this method, large waveform distortion which can be allowed in optical communication application is observed, but no waveform distortion is generated by this method and the signal light is amplified excellently.
