GHz,1 432/1 544 nm all optical wavelength conversion was demonstrated by using a nonlinear optical mirror and the simulated predictions were in good agreement with the experimental results.

This dissertation focuses on investigations of key technologies and issues in ultrahigh-speed photonics networks, included ultra-short-pulse generation technology, all optical wavelength conversion, ultra-fast multiplexing/demultiplexing systems and all optical switching network structures.

Study on all-optical wavelength conversion by using idle light;

Two types of all-optical wavelength conversion by coupling attenuation;

Since the all-optical wavelength conversion at present is realized by using Semiconductor Optical Amplifier (SOA), the all-optical wavelength conversion based on Erbium-doped Fiber Amplifier and Nonlinear Dispersion Fiber (EDFA+NDF) is put forward in the paper.

A novel all-optical wavelength conversion (AOWC) based on the cascaded sum frequency generation (SFG) and difference frequency generation (DFG) in LiNbO3 waveguides have been theoretically studied.

Experimental investigation of a novel tunable all-optical wavelength converter with a double-ring cavity;

High-precision, ultrastable, high-integrated module for novel all-optical wavelength converter was presented, and the parameters of the converter can be monitored and controlled easily with the module based on the series communication between the singlechip and PC.
