100-GHz FrOFDM-Based Serial-to-Parallel Converter and QPSK Modulation Format Applicability

摘要

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.
