本文报道利用fs光脉冲的多波长多路分割(WDM)法。在过去的WDM光传输方式中,各通道需要波长不同的光源。而本文的特点是用单一fs激光器作多波长光源,空间调制多波长信号。在空间并行型光调制器上用衍射光栅将fs光脉冲的宽光谱分光。将各通道光用光调制器独立调制反射后,再通过衍 This paper reports a multi-wavelength multi-path segmentation (WDM) method using fs optical pulses. In the past WDM optical transmission mode, each channel requires a different wavelength of light source. The characteristic of this paper is to use a single fs laser as a multi-wavelength light source to spatially modulate multi-wavelength signals. Splitting the wide spectrum of fs light pulse with a diffraction grating in a spatial parallel light modulator. The channel light modulation with light modulator independent reflection, and then through the diffraction
