Abstract

Power efficient optical serial-to-parallel conversion is proposed using a linear technique based on Fractional OFDM scheme. A Fractional OFDM can mediate between N-OTDM and OFDM without any nonlinear signal processing and it is expected to incorporate both benefits of the densest serial and parallel features of N-OTDM and OFDM as well as power efficiency of a linear technique. The preliminary operation of serial-to-parallel conversion is verified so that a 10 GHz sine wave serial signal could be optically sampled by triple Nyquist pulses and be converted to three parallel intensity modulated signals at three Fr-OFDM channels.
