Abstract

Multi-wavelength fiber lasers have versatile applications including fiber optic sensing, instrumentation, optical signal processing and especially in the design of optical division multiplexing systems (WDM). Up to date, most research effort has been reported that the generation of dual-wavelength pulses from an actively mode-locked fiber lasers. Although the actively mode-locked fiber lasers have advantages such as high repetition rates, narrow linewidth and large number of wavelengths, it could not obviate the drawbacks of weak peak power, broad pulse width, and expensiveness as a modulator is required to be inserted in the cavity.
