We report efficient cascaded Raman generation and signal amplification at 1.3 ㎛ achieved in a ring resonator constructed solely from fiber components, i.e. fusion WDM couplers. Low-loss single-mode fiber with moderate GeO₂ content (18 mole %) is used as an active medium and pumped by a Nd:YAG laser at 1.064 ㎛. In a resonant cascaded geometry, this generates the third Stokes line at 1.24 ㎛, which acts as a pump for signal wavelength around 1.3 ㎛. A DFB laser operating at 1.315 ㎛ is used to provide an input signal. An output signal powers up to 20 dBm (100 ㎽) with a 28 dB Raman gain are attained, where the Nd:YAG pump power is 3.4 W. It is also shown experimentally that it is important to use optical filters to suppress feedback from the resonator, permitting high Raman gain and good signal quality.
