Abstract
A proposed arrayed waveguide grating (AWG) demultiplexer (DEMUX) design for coarse wavelength division multiplexing (CWDM) networks is described in which two cascaded AWG are used to obtain a flat-top passband with steep roll-off and wide channel bandwidth. Scalar electromagnetic simulations are used to verify the operation of four-and eight-channel devices satisfying the standard International Telecommunication Union (ITU) grid for CWDM. The devices show good channel uniformity with very low crosstalk in the range of −60 dB in the case of the four-channel demultiplexer.
