An efficient technique for analyzing transmission characteristics of arrayed waveguide grating multiplexers

摘要

An efficient technique is presented for analyzing transmission characteristics of arrayed waveguide grating (AWG) multiplexers. As an example, calculations using this technique are performed for a polymer 33 x 33 AWG multiplexer around the central wavelength of 1.55 mum with the wavelength spacing of 0.8 nm. Computed results show that this technique possesses high accuracy for analyzing the power pro. le, diffraction efficiency, transmission spectrum, free spectral range and crosstalk of the AWG multiplexer.
