DUAL WAVELENGTH FIBER LASER AND ITS APPLICATION IN MICROWAVE GENERATION (Invited Paper)
In this paper, two approaches to achieve stable dual-wavelength single-longitudinal-mode operation and microwave signal generation by fiber Bragg grating based fiber lasers is proposed and experimentally demonstrated respectively. The first approach utilizes the spatial hole burning effect, which supports the dual wavelength operation in homogeneous gain medium. The numerical simulation and experimental results of a dual wavelength erbium-doped fiber laser with simple linear cavity are reported. The laser output with a wavelength spacing of 27pm is heterodyned on a photodiode to generate a microwave signal of 3.389GHz with frequency stability better than 3MHz. In the second one,dual-wavelength fiber laser with novel distributed feedback structure is also experimentally demonstrated.Stable microwave signal at 38.6955GHz is obtained, with a 3-dB bandwidth ＜10kHz and frequency drift ＜5MHz at room temperature without any feedback mechanism.
