<p>An optical signal add-drop multiplexer and an optical signal processing method. The optical signal add-drop multiplexer (1) comprises an input light coupling unit (11), a second-order nonlinear optical waveguide (12) and an output light coupling unit (13), wherein the input light coupling unit (11) receives input signal light and generates a path of continuous pumping light and at least one path of pulse pumping light. In the second-order nonlinear optical waveguide (12), the input signal light and the at least one path of pulse pumping light are converted into signal conversion light, and the input signal light, the at least one path of pulse pumping light, as well as the continuous pumping light are converted into at least one path of idle signal light. The output light coupling unit (13) outputs the at least one path of idle signal light as at least one path of drop signal light, and outputs the signal conversion light. By means of the effects of combining the parameter attenuation of the second-order nonlinear optical waveguide with the wavelength conversion, the optical signal add-drop multiplexer and the optical signal processing method realize the processing of optical signals in all-optical time domains and improve the speed and the flexibility of network nodes.</p> |
