Abstract
A family of ultra-dense wavelength division multiplexing/demultiplexing devices are disclosed. In the case of an ultra-dense wavelength division multiplexing device, a wavelength division multiplexing device is used for combining at least one plurality of monochromatic optical beams into a corresponding at least one single, multiplexed, polychromatic optical beam, wherein the wavelength division multiplexing device has an input element and an output element. A plurality of optical input devices is disposed proximate the input element, wherein each of the plurality of optical input devices communicates a plurality of monochromatic optical beams to the wavelength division multiplexing device for combining the plurality of monochromatic optical beams into a single, multiplexed, polychromatic optical beam. A corresponding plurality of optical output devices is disposed proximate the output element, wherein each of the plurality of optical output devices receives a corresponding single, multiplexed, polychromatic optical beam.
