Detailed study of four-wave mixing in Raman DFB fiber lasers.
We both experimentally and numerically studied the ultra-compact wavelength conversion by using the four-wave mixing (FWM) process in Raman distributed-feedback (R-DFB) fiber lasers. The R-DFB fiber laser is formed in a 30 cm-long commercially available Ge/Si standard optical fiber. The internal generated R-DFB signal acts as the pump wave for the FWM process and is in the normal dispersion ran...
متن کاملFour-wave mixing in microstructure fiber.
We report what we believe to be the first experimental demonstration of nondegenerate four-wave mixing in a microstructure fiber. The effect of the chi((3)) nonlinearity is enhanced in such a fiber because of the small core area, and we achieve phase matching by operating near the zero-dispersion wavelength (?750 nm) . We have observed parametric gains of more than 13 dB in 6.1-m-long fiber wit...
متن کاملPhase noise of four-wave mixing in semiconductor lasers
A simple theoretical analysis shows that the linewidth of the conjugate wave produced in four-wave mixing in semiconductor lasers is equal to the linewidth of the probe plus four times the linewidth of the pump. Experimental results in good agreement with the theory are presented. This result implies an enormous enhancement in the phase noise of the conjugate wave and sets a limitation on some ...
متن کاملWavelength conversion in silicon using Raman induced four-wave mixing
Silicon integrated optics has emerged as an attractive technology for realizing passive devices because of the efficient silicon-on-insulator sSOId guiding structures and foundry compatible processing technology. However, silicon is generally perceived to be devoid of active optical properties that are needed to realize more sophisticated optical functions such as, amplification and wavelength ...
متن کاملHigh-Power Continuous-Wave Directly-Diode-Pumped Fiber Raman Lasers
We describe novel fiber Raman lasers pumped directly by spectrally combined high power multimode laser diodes at ∼975 nm and emitting at ∼1019 nm. With a commercial multimode graded-index fiber, we reached 20 W of laser output power with a record slope efficiency of 80%. With an in-house double-clad fiber, the beam quality improved to M = 1.9, albeit with lower output power and slope efficiency...
