摘要： A photonic integrated circuit includes an optical coupling device situated between two successive interconnection metal levels. The optical coupling device includes a first optical portion that receives an optical signal having a transverse electric component in a fundamental mode and a transverse magnetic component. A second optical portion converts the transverse magnetic component of the optical signal into a converted transverse electric component in a higher order mode. A third optical portion separates the transverse electric component from the converted transverse electric component and switches the higher order mode to the fundamental mode. A fourth optical portion transmits the transverse electric component to one waveguide and transmits the converted transverse electric component to another waveguide.

摘要： An arrayed waveguide grating multiplexer/demultiplexer includes an array of optical waveguides ordered in sequence from a shortest waveguide up to a longest waveguide, and identical phase shifters configured to be controlled by a same control signal. Each phase shifter increases/decreases an optical path of an optical waveguide by the same quantity based on the control signal.

摘要： A photodiode includes an active area formed by intrinsic germanium. The active area is located within a cavity formed in a silicon layer. The cavity is defined by opposed side walls which are angled relative to a direction perpendicular to a bottom surface of the silicon layer. The angled side walls support epitaxial growth of the intrinsic germanium with minimal lattice defects.

摘要： A vertical photodiode includes an active area. The contacting pads for the diode terminals are laterally shifted away from the active area so as to not be located above or below the active area. The active area is formed in a layer of semiconductor material by a lower portion of a germanium area that is intrinsic and an upper portion of the germanium area that is doped with a first conductivity type. The vertical photodiode is optically coupled to a waveguide formed in the layer of semiconductor material.
