Abstract
An optical equalizer comprises a plurality of serially concatenated filter elements the phase and modulation depth of which can be individually tuned. The filter elements are tuneable in order to generate a desired optical equalization function. Each of the filter elements is a three arm interferometer and each is fabricated utilizing integrated waveguide technology.
