Flexible power-efficient Nyquist-OTDM transmitter, using a WSS and time-lens effect

Power-efficient, flexible, Nyquist 4.88-ps sinc-pulses generation and OTDM multiplexing is demonstrated, using fractional Fourier transform subcarriers and time-lens effect. OTDM users are generated and multiplexed by a WSS, without rectangular spectral shaping.
