Abstract (en)
[origin: WO03043233A1] The invention concerns a dynamic spectral equalizer, comprising: means for demultiplexing an incident beam of at least two multiplexed wavelengths including at least a first dispersive optical element, so as to form a spatial multiplex of said at least two wavelengths; means for attenuating the spectral power associated with at least one wavelength of said spatial multiplex, including at least a programmable semitransparent holographic mirror, so as to form an equalized spatial multiplex; means for multiplexing said equalized spatial multiplex, including at least a second dispersive optical element, so as to form an equalized beam of at least two multiplexed wavelengths.
