    摘要: An apparatus includes a magnetic core, a ground node, and one or more vias to provide a connection between the magnetic core and the ground potential. The magnetic core includes a first magnetic layer and a second magnetic layer. In addition, the apparatus may include a conductive pattern. The conductive pattern may be at a third layer between the first and second magnetic layers. The apparatus may be included in inductors, transformers, transmission lines, and other components using ferromagnetic cores or shields. Such components may be integrated on a chip or die.

    摘要: The optical modulator may include a strained layer of SiGe to confine carriers in a quantum well. The strained layer of SiGe may be doped with arsenic to provide electrons. The optical modulator may receive an optical signal and modulate the received signal by altering the absorption coefficient of the strained layer of SiGe responsive to an electrical signal. The optical modulator device device may be suitable for use in chip-to-chip and on-chip interconnections.
