Abstract
Sinc-shaped Nyquist pulses have a rectangular spectrum. In the spectral domain, adjacent Nyquist wavelength division multiplexed (WDM) channels can be multiplexed without any guard band. Theoretically, they can be used to transmit the maximum possible symbol and data rate. The demultiplexing of channels requires filters with transfer functions that are as close as possible to rectangular shapes. Here we present the successful demultiplexing of rectangular-shaped optical Nyquist dense wavelength division multiplexed channels, modulated with an advanced modulation format, with an eight-channel integrated silicon photonics device.
