Abstract

The invention relates to a high-speed all-optical wavelength conversion integrated device and belongs to the technical field of photoelectron. The integrated high-speed all-optical wavelength conversion device mainly comprises a cascaded structure of two semiconductor optical amplifiers and an electroabsorption modulator. By utilizing a cross-gain modulation effect in a first semiconductor optical amplifier, a signal on pumping light is modulated onto detecting light with a different wavelength; by utilizing an electroabsorption effect of the electroabsorption modulator, the pumping light is filtered; and by utilizing a self-gain effect of a second semiconductor optical amplifier, a pattern effect of outputting an optical signal in the high-speed wavelength conversion process is compensated, so that the high-speed all-optical wavelength conversion is realized. In the invention, the electroabsorption modulator is used in the all-optical wavelength conversion device for realizing a filtering function for the first time. When completing the high-speed all-optical wavelength conversion, the integrated high-speed all-optical wavelength conversion device has the characteristics of small size and easiness for integration and can be applied to a routing technology of the next generation of optical network.
