A new-style silica planar lightwave circuit (PLC) hybrid integrated triplexer, which can demultiplex 1490-nm download data and 1550-nm download analog signals, as well as transmit 1310-nm upload data, is presented. It combines SiO2 arrayed waveguide gratings (AWGs) with integrated photodetectors (PDs) and a high performance laser diode (LD). The SiO2 AWGs realize the three-wavelength coarse wavelength division multiplexing (CWDM). The crosstalk is less than -40 dB between the 1490- and 1550-nm channels, and less than -45 dB between 1310- and 1490- or 1550-nm channels. For the static performances of the integrated triplexer, its upload output power is 0.4 mW, and the download output photo-generated current is 76 \mu A. In the small-signal measurement, the upstream -3-dB bandwidth of the triplexer is 4 GHz, while the downstream -3-dB bandwidths of both the analog and digital sections reach 1.9 GHz.
