Abstract
This paper has proposed new materials based conventional arrayed waveguide grating (AWG) devices such as pure silica glass (SiO 2), Lithium niobate (LiNbO 3), and gallium aluminum arsenide (Ga (1-x) Al (x) As) materials for multiplexing and demultiplexing applications in interval of 1.45 µm to 1.65 µm wavelength band, which including the short, conventional, long, and ultra long wavelength band. Moreover we have taken into account a comparison between these new materials within operating design parameters of conventional AWG devices such as diffraction order, length difference of adjacent waveguides, focal path length, free spectral range or region, maximum number of input/output wavelength channels, and maximum number of arrayed waveguides. As well as we have employed these materials based AWG to include Multi band applications under the effect of ambient temperature variations.
