DYNAMIC SPECTRAL EQUALIZER USING A PROGRAMMABLE HOLOGRAPHIC MIRROR |
摘要 |
The invention relates to a dynamic spectral equaliser comprising: means of demultiplexing an incident beam with at least two multiplexed wavelengths, comprising at least one first dispersive optical element, so as to form a spatial multiplex of the said at least two wavelengths; means of attenuating the spectral power associated with at least one wavelength of the said spatial multiplex, comprising at least one programmable semi-transparent holographic mirror, so as to form an equalised spatial multiplex; means of multiplexing the said equalised spatial multiplex, comprising at least one second dispersive optical element, so as to form an equalised beam with at least two multiplexed wavelengths. |
