A novel fractional orthogonal frequency division multiplexing (FrOFDM)-based 100-GHz serial-to-parallel (S-P) converter is experimentally demonstrated. A 10-GHz sinusoidally modulated Nyquist-optical time division multiplexing serial signal, with 100-GHz repetition rate, is optically restored after S-P conversion. In addition, the performances for quadrature phase shift keying (QPSK) modulation have been numerically evaluated. Also in this case, the error vector magnitude values and the constellation map of 100-GHz QPSK serial signals demonstrate a successful S-P conversion.
