Abstract: An electro-optic (E/O) device includes an asymmetric optical coupler having an input and first and second outputs, a first optical waveguide arm coupled to the first output of the first asymmetric optical coupler, and a second optical waveguide arm coupled to the second output of the first asymmetric optical coupler. At least one E/O amplitude modulator is coupled to at least one of the first and second optical waveguide arms. An optical combiner is coupled to the first and second optical waveguide arms downstream from the at least one E/O amplitude modulator.

Abstract: A semiconductor device may include a semiconductor wafer, and a reference circuit carried by the semiconductor wafer. The reference circuit may include optical DUTs, a first set of photodetectors coupled to outputs of the optical DUTs, an optical splitter coupled to inputs of the optical DUTs, and a second set of photodetectors coupled to the optical splitter. The optical splitter is to be coupled to an optical source and configured to transmit a reference optical signal to the first set of photodetectors via the optical DUTs and the second set of photodetectors.

Abstract: An electro-optic device may include a photonic chip having an optical grating coupler at a surface. The optical grating coupler may include a first semiconductor layer having a first base and first fingers extending outwardly from the first base. The optical grating coupler may include a second semiconductor layer having a second base and second fingers extending outwardly from the second base and being interdigitated with the first fingers to define semiconductor junction areas, with the first and second fingers having a non-uniform width. The electro-optic device may include a circuit coupled to the optical grating coupler and configured to bias the semiconductor junction areas and change one or more optical characteristics of the optical grating coupler.

Abstract: An integrated electronic device includes a substrate having an opening extending therethrough. The substrate includes an interconnection network, and connections coupled to the interconnection network. The connections are to be fixed on a printed circuit board. An integrated photonic module is electrically connected to the substrate, with a portion of the integrated photonic module in front of or overlapping the opening of the substrate. An integrated electronic module is electrically connected to the photonic module, and extends at least partly into the opening of the substrate. The electronic module and the substrate may be electrically connected onto the same face of the photonic module.

Abstract: A method is for aligning an electro-optic device. The method may include initially positioning an optical fiber array adjacent to optical grating couplers, and actively aligning the optical fiber array relative to the optical grating couplers in a yaw direction and a roll direction to determine a yaw and roll alignment at a first operating wavelength. The method may include actively aligning the optical fiber array relative to optical grating couplers in an x direction and a y direction to determine a first x and y alignment at the first operating wavelength, determining a second operating wavelength, and actively aligning the optical fiber array again relative to the optical grating couplers in the x direction and y direction to determine a second x and y alignment at the second operating wavelength.
