摘要: The present invention relates to an adjustable optical signal delay module, particularly to a module, which adjusts power of an amplified spontaneous emission generated by a semiconductor optical amplifier and reversely feeds the adjusted amplified spontaneous emission back to the semiconductor optical amplifier to vary a group refractive index of the semiconductor optical amplifier and delay the timing of an optical signal, whereby the present invention can replace the pump laser conventionally required by a CPO mechanism. In the present invention, the feedback optical loop comprises a variable optical attenuator, an optical filter, and optical circulators. An user can control the delay timing of optical signals via adjusting optical power in the feedback optical loop. The present invention can decrease the fabrication cost of an optical signal delay module and reduce the volume thereof.
