A soliton pulse generator is formed by providing an input continuous wave, stimulating Brillouin scattering of an input wave having a frequency determined by the frequency of the input continuous wave to generate a backscattered wave, coupling a continuous wave having a frequency determined by the input continuous wave with the backscattered wave to generate a sinusoidal output signal, and then compressing the sinusoidal output to form a soliton pulse train. Because the wavelength shift of the backscattered wave is essentially independent of the input wavelength and power, coupling of the second wave and the backscatterred wave results in a highly stable and controllable sinusoidal output signal. A highly stable and controllable soliton pulse train is provided by compressing the sinusoidal signal with use of a dispersion decreasing fiber or with use of an alternative pulse compressing device. |
