In this paper, an athermal polarization-independent 49 channel arrayed-waveguide grating (AWG) multiplexer relying on a UV curable all-polymer approach was designed and fabricated by simple direct Ultraviolet photolithography process. The transmission properties of the AWG around the central wavelength of 1550.918nm with the wavelength spacing of 0.8nm were optimized by Matlab programming. By properly...
