Paper Abstract

The backscattering spectrum of optical fiber G652 (SiO2) has been researched, in the Stokes region the first order and second order Raman spectrum have been observed and the ZX band backscattering spectrum is first observed. The small signal pump on/off Raman gain spectrums have been measured by the 1427.2nm Raman laser and Q8384 optical spectrum analyzer, during different pump power. The Raman gain is 19dB and gain band width is 96nm (1440nm-1536nm) during the pump power is 700mw. The liquid-core optical fiber is made ofhollow quartz fiber filling organic liquid materials including C6H6, CS2, CCl4 and so on. The constitution and proportion of liquid materials are designed. Raman effect in liquid-core optical fiber is researched. The liquid-core optical fiber Raman amplifier are designed by using FRA optimum design software. This observed Stokes frequency shift is characteristic of the 992-cm-1, 656-cm-1, and 459cm-1 lines in C6H6 CS2, andCCl4. The Raman laser (1427mm) is used as pumping laser. A mini-ASE light source is used as signal source. The Raman spectrum has been measured by OSA Q8384 in liquid-core optical fiber. The Raman amplified bandwidth in liquid-core optical fiber is researched. The relations between the pumping threshold and liquid-core optical fiber length are attained.
