摘要

A device for expanding the wavelength band of an optical component is disclosed. The device has a beam splitter for splitting a wavelength division multiplexed beam into two beams at a desired separation angle. An optical grating separates the two beams into spectral components for each beam. The spectral components are focused on a receiving surface. The separation angle between the two beams expands the wavelength band of the WDM signal.
