Paper Abstract

I propose a real-time demultiplexing method of terahertz-wave OFDM signal, which utilizes the optical technology. The received and amplified electrical OFDM signal is transferred into an optical OFDM signal through an optical modulator. Then, the optical OFDM signal is processed with an integrated-optic DFT circuit, which is mainly composed of a slab star coupler. This optical DFT circuit is compact, and can demultiplex up to a 10 × 10 Gbaud (100 Gbaud) optical OFDM signal. I report the operating principle of the method and some preliminary experimental results.
