    • Polarization modulator devices (300) can be formed to take advantage of multi-layered semiconductor structures. High quality epitaxial layers (26) of monocrystalline materials can be grown overlying monocrystalline substrates (22) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer (24) comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer (28) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer.

    • A communications system (10 and 12) in which a communications channel is defined at least in part by an electromagnetic wave (78) having a carrier frequency and an electric field vector, the extremity or terminus of which traces a non-linear periodic path at a rotation frequency less than the carrier frequency and greater than zero from the perspective of an observer looking into the axis of propagation of the wave. The transmitter (10) of the communications system launches a wave (78) having such characteristics and modulated with information in a suitable manner. The receiver (12) of the communications system is sensitive to the periodic path and rotation frequency. The combination of the periodic path and the carrier frequency provides selectivity that can be used to define multiple communications channels.
