Abstract
A novel method to achieve phase-matched light amplification in a birefringent fiber via the three-wave mixing is proposed by using frequency shift change due to the stress applied to the fiber. It is confirmed that the signal power from a cw laser diode at λ=1.292 μm is amplified by 6.1×103 times in the birefringent fiber pumped with a Q-switched Nd: yttrium aluminum garnet laser at λ=1.064 μm. This will provide a new fiber-optic light signal amplifier having a good tolerance for variation of signal wavelengths.Keywords
