Ultra wide band suppressed carrier optical single side band signal generation.

摘要

Optical beam generator, comprising a carrier beam input (1) and a signal beam input (2). A beam splitter (3) is connected to the carrier beam input (1) and the signal beam input (2) to obtain quadrature carrier beam components and quadrature signal beam components. First and second nonlinear photonic crystals (4, 5) are arranged to mix associated quadrature beam components of the quadrature carrier beam components and the quadrature signal beam components into optical double side band signals. A combiner element (6; 15) is arranged to receive the optical double side band signals and to provide an optical single side band signal using coherent addition or coherent subtraction.
