Rapid Progress of a Thermal Arrayed Waveguide Grating Module for Dense Wavelength Division Multiplexing Applications

In the present paper, we have proposed a thermal planar arrayed waveguide grating (AWG) module for dense wavelength division multiplexing (DWDM) which is composed of one of the following material as a core such as Pure silica glass (SiO₂), Lithium niobate (LiNbO3), and gallium aluminum arsenide (Ga_{(1- x)}Al_(x)As)/Polyhexafluoro isopropyl 2-fluoroacrylate dibutyl phathalate (PHFIP 2-FA-DBP) used as over cladding material/Polyhexafluoro isopropyl 2-fluoroacrylate (PHFIP 2-FA) used as under cladding material, hybrid materials on a silicon substrate has parametrically investigated over wide range of the affecting parameters. multiplexing technique is processed where multi channels in ultra dense wavelength division multiplexing in a thermal AWG module. We have theoretically investigated the temperature dependent wavelength shift of the AWG depends on the refractive indices of the materials and the size of the waveguide. A thermalization of the AWG can be realized by selecting proper values of the material and structural parameters of the device. We have taken into account the increased number of transmitted channels within DWDM technique over a thermal planar AWG of hybrid materials. The thermal effects of different hybrid materials employed in the fabrication of AWG are studied deeply and parametrically for the good performance of such AWG.
