SPECTRALLY-SHAPED OPTICAL COMPONENTS USING A WAVELENGTH-DISPERSIVE ELEMENT AND A REFLECTIVE ARRAY

摘要

An optical component based on a wavelength-dispersive element in conjunction with reflective elements (68N) to provide wavelength-sensitive control multi-wavelength light signals such as wavelength division multiplexed light signals. Both static reflective elements (68N) 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.
