Abstract: 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.

Abstract: A three-dimensional photonic integrated structure includes a first semiconductor substrate and a second semiconductor substrate. The first substrate incorporates a first waveguide and the second semiconductor substrate incorporates a second waveguide. An intermediate region located between the two substrates is formed by a one dielectric layer. The second substrate further includes an optical coupler configured for receiving a light signal. The first substrate and dielectric layer form a reflective element located below and opposite the grating coupler in order to reflect at least one part of the light signal.

Abstract: A method for making an electro-optic device includes forming a first photonic device having a first material in a first photonic layer over a substrate layer. A second photonic layer with a second photonic device is formed over the first photonic layer and includes a second material different than the first material. A dielectric layer is formed over the second photonic layer. A first electrically conductive via extending through the dielectric layer and the second photonic layer is formed so as to couple to the first photonic device. A second electrically conductive via extending through the dielectric layer and coupling to the second photonic device is formed. A third electrically conductive via extending through the dielectric layer, the second photonic layer, and the first photonic layer is formed so as to couple to the substrate layer.

Abstract: An electro-optic device may include a photonic chip including an insulator layer, and a semiconductor layer over the insulator layer and defining an optical grating coupler. The optical grating coupler may have a series of alternating curved ridges and valleys. The optical grating coupler has first and second sides and a medial portion. The medial portion has a medial grating period T based upon a targeting wavelength. One or more of the first and second sides have a side grating period different than T.

Abstract: 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 control signal.

Abstract: A multi-mode interference device may include a body having an optical axis and configured to generate a stationary optical interference pattern from an incoming optical wave. The body may include ribs being parallel to the optical axis and being spaced apart to define a pitch and cause an optical coupling between the ribs.
