We have proposed a novel multi-band orthogonal frequency division multiplexing and passive optical network (OFDMA-PON) architecture using signal-to-signal beat interference cancellation receivers based on balanced detection at both the optical line terminal and the optical network units (ONUs). Simulation of the full-duplex system with 20 km SSMF(More)
A novel approach to generate the flattened optical frequency comb (OFC) with tunable frequency spacing is proposed. The proposed generator consists of two cascaded polarization modulators driven by two radio frequency signals with different frequencies. By adjusting the parameters, 9, 12, and 16 comb lines can be generated with tunable frequency spacing.(More)
A novel full-duplex hybrid access link with 10 Gbit/s 16-ary quadrature amplitude modulation (16-QAM) wired and wireless converged signal is proposed, which can provide PON access or RoF-based wireless access alternately with centralized lightwave source. The converged signal, consisting of the 10 Gbit/s 16-QAM baseband optical signal and two optical local(More)
