Spectrally-shaped optical components using a wavelength-dispersive element and a reflective array

摘要

The present invention features an optical component based on a wavelength-dispersive element in conjunction with reflective elements to provide wavelength-sensitive control multi-wavelength light signals such as wavelength division multiplexed (WDM) light signals. Both static reflective elements and movable (dynamic) reflective elements are described. Optical devices such as gain-flattening filters and dynamically configurable wavelength selective routers with built-in gain flattening filters are described.
