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

摘要

In the present paper, we have proposed a thermal planar arrayed waveguide grating (AWG) module for densewavelength division multiplexing (DWDM) which is composed of one of the following material as a core such asPure 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 claddingmaterial/Polyhexafluoro isopropyl 2-fluoroacrylate (PHFIP 2-FA) used as under cladding material, hybridmaterials 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 athermal AWG module. We have theoretically investigated the temperature dependent wavelength shift of theAWG depends on the refractive indices of the materials and the size of the waveguide. A thermalization of theAWG can be realized by selecting proper values of the material and structural parameters of the device. We havetaken into account the increased number of transmitted channels within DWDM technique over a thermal planarAWG of hybrid materials. The thermal effects of different hybrid materials employed in the fabrication of AWGare studied deeply and parametrically for the good performance of such AWG.
