【摘要】 报道了一种新的全光波长变换的方法：利用频谱分割光纤放大器的自发辐射噪声的方法获得连续可调非相干光源，在色散位移光纤中，实现了基于非相干光与相干光之间四波混频机理的全光波长变换。用这种方法实现了对５Ｇｂｉｔ／ｓ归零码光信号的波长变换，最高变换效率为－２４ｄＢ，四波混频光的波长最大变换范围约为３．４ｎｍ。更多还原

【Abstract】 A novel method of wavelength conversion based on four wave mixing in a dispersion shifted fiber using a spectrum sliced fiber amplifier light source is demonstrated. Utilizing the wavelength region around the zero dispersion wavelength of a fiber, a coherent light modulated by 5 Gbit/s RZ signal is converted with a conversion efficiency of -24 dB。更多还原
