Design of a multiwavelength optical buffer for optical networks by using a 1D defect ternary photonic multilayer structures

In this paper, a multiwavelength optical buffer is proposed for optical communication networks. This buffer is based on 1D defect ternary photonic multilayer structure. This buffer will generate different delay times for different wavelengths. The wavelength to be buffered by this buffer can be changed and controlled by changing the temperature of the defect layer. The wavelength range of operation of this buffer can be changed by changing the structural parameters. This same optical buffer can be used for several wavelengths by changing the temperature of the defect layer. It has also been shown that to design a buffer with a different delay time, the thicknesses of the material layers and/or number of periods in this structure can be changed.
