摘要

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 SiO_2 arrayed waveguide gratings(AWGs) with integrated photodetectors(PDs) and a high performance laser diode(LD).The SiO_2 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 76μA.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.
