Abstract
A modulator assembly for modulating light comprising a first and a second electro-absorption modulator which each at least substantially only act on a polarization component of incident light; a light generating assembly for generating light which includes a first and a second polarization component; a first electro-absorption modulator for modulating the light generated by the light generating assembly, wherein the first electro-absorption modulator at least substantially only modulates the first polarization component of the light, so that the light exiting from the first electro-absorption modulator includes a modulated and an unmodulated polarization component; a polarization converter for changing the polarization direction of the light exiting from the first electro-absorption modulator. The light exiting from the polarization converter couples into the second electro-absorption modulator and is polarized such that by means of the second electro-absorption modulator a modulation at least substantially is effected only of the previously unmodulated polarization component.
