We have proposed and experimentally demonstrated all-optical multiplexing (MUX)-format
conversion from Nyquist optical time division multiplex (OTDM) to Nyquist wavelength
division multiplex (WDM). The system is simply configured with a straight-type phase
modulator (PM) driven by a sinusoidal wave and an optical Nyquist filter. In the theoretical
investigation, it is proved that the single Nyquist signal is completely converted to Nyquist
WDM signal, which consists of two half-baud-rate signals with different carrier frequencies …
