More Information
Summary:A module handles beams having multiple channels in an optical network. The module has a dispersion element, a liquid crystal (LC) based switching assembly, and photodetectors. The dispersion element is arranged in optical communication with the beams from inputs and is configured to disperse the beams into the channels across a dispersion direction. The switching assembly is arranged in optical communication with the channels from the dispersion element and is configured to selectively reflect the channels using electrically switchable cells of one or more LC-based switching engines. The photodetectors are arranged in optical communication with the dispersion element, and each are configured to receive selectively reflected channels for optical channel monitoring. Outputs can be arranged in optical communication with the dispersion element and can be configured to receive selectively reflected channels for wavelength selective switching.
