Paper Abstract

This paper has analyzed the random phase errors of AWG (array waveguides grating) induced by fabricate processing and their affects on crosstalk level of AWG between non-adjacent channels theoretically. And a very useful formula which can estimate crosstalk level has been proposed. By using this formula, the DWDM (Dense Wavelength De-multiplexer Multiplexer) components based on AWG can be optimized to reduce their crosstalk level. Finally, a very good design example which non-adjacent crosstalk is -40dB by using this formula has been given.
