A Flat Fiber Raman Amplifier by Optimizing a Single-Wavelength Laser Diode

Abstract:

Gain-flatness is one of the crucial parameters for the application of fiber Raman amplifier (FRA). To obtain the ideal gain-flatness within the wide spectrum, the devices should be optimized in a FRA system. In this article, rather than a complicated design reported in the traditional schemes, we adopt a single-wavelength laser diode to flatten the gain spectrum of FRA through optimize its pumping power and wavelength simply. The numerical results by simulation show that the gain-flatness of the designed FRA system is controlled within ±1 dB in the range of 1500 nm ~1560 nm by a laser diode with 1435 nm and 250 mW.
