Optical gain equalizer
An optical equaliser (20) comprises a plurality of serially concatenated filter elements (22) the phase and modulation depth of which can be individually tuned. The filter elements are tuneable in order to generate a desired optical equalisation function. Each of the filter elements is a three arm i...

| Zusammenfassung: | An optical equaliser (20) comprises a plurality of serially concatenated filter elements (22) the phase and modulation depth of which can be individually tuned. The filter elements are tuneable in order to generate a desired optical equalisation function. Each of the filter elements is a three arm interferometer and each is fabricated utilising integrated waveguide technology. |
