A new triplexing filter based on a silica direction coupler and an arrayed waveguide grating is presented. Using a combination of a direction coupler and an arrayed waveguide grating, a channel is multiplexed and 1490- and channels are demultiplexed for fiber-to-the-home. The direction coupler is used to coarsely separate the channel from the 1490- and channels. Subsequently, an arrayed waveguide grating is used to demultiplex the 1490- from channel. The simulated spectra show the bandwidth of for the channel and 20 and for the 1490- and channels. The insertion loss is only for and for 1490 and . The crosstalk between the 1490- and channels was less than .
