Demultiplexing experiment using arrayed waveguide grating for optical frequency interleaved DWDM mm-wave fiber-radio systems

摘要

In this report, we experimentally demonstrate demultiplexing 25-GHz separated 2-channel optical DSB signals modulated by a 60-GHz mm-wave carrying a 156-Mbps-DPSK data using an arrayed-waveguide grating (AWG) for DWDM mm-wave fiber-radio systems by optical frequency interleaving. The configuration of demultiplexer consists of a high-finesse Fabry- Perot etalon, the AWG with 2-input and N-output waveguides and an optical circulator. The power penalty after demultiplexing channels 1 and 2 were less than 0.5 dB. No noticeable power penalty was observed after 25-km SMF transmission. This is because the carrier and only one of the sidebands are detected in the proposed demultiplexing scheme.
