Abstract
An example photonic integrated circuit includes a wavelength selective switch (WSS), the WSS including an input port configured to receive a plurality of optical signals. Each optical signal has a center wavelength and a signal bandwidth, and the center wavelength of each optical signal is different from the center wavelengths of the other optical signals. The WSS also includes an output port and a spectral filter configured to switch an optical signal of the plurality of optical signals to the output port based on the center wavelength of the optical signal.
