Abstract :
An easily scalable eight channel photonic integrated circuit to demultiplex an optical orthogonal frequency-division multiplexing (OFDM) symbol is presented. It is designed and fabricated using a silicon photonic platform. The measured filter response is in close agreement with the modeled results for an ideal device. Emulation using the measured response of the fabricated filter shows that the filter is capable of demultiplexing optical OFDM symbols comprising eight sub-carriers, each operating at 13.5 GBd.
