More Information
Summary:The present invention provides a photonic device such as a variable optical attenuator, in which two signal components, propagating in modes of two different polarization states, are converted to two different modes of the same polarization state prior to modulation. The modulation of both components is performed by a single device which applies the same modulation strength to both components. The two signal components can be converted back to propagate in the two different polarization states following modulation.
