  • Patent number: 8731346
    Abstract: Embodiments of the present disclosure provide optical connection techniques and configurations. In one embodiment, an apparatus includes a substrate, a laser device formed on the substrate, the laser device including an active layer configured to emit light, and a mode-expander waveguide disposed on the substrate and butt-coupled with the active layer to receive and route the light to a waveguide formed on another substrate. Other embodiments may be described and/or claimed.

  • Publication number: 20140086527
    Abstract: An optical coupler includes a double-sided planar substrate having a lens manufactured on one side and a mode expander on the other side. The mode expander is coupled to a mirror that redirects light between the mode expander and the lens. The mirror is lithographically aligned with the lens. The substrate is optically transparent to a target wavelength to be used for optical signaling. The lens can be a lens array, in which case there can be a mirror for each lens in the array. The mode expander can couple an optical signal to a planar lightwave circuit (PLC) or other optical circuit. The lens on the optical coupler can interface with a single-mode optical fiber.

  • Publication number: 20130279845
    Abstract: PLC architectures and fabrication techniques for providing electrical and photonic integration of a photonic components with a semiconductor substrate. In the exemplary embodiment, the PLC is to accommodate optical input and/or output (I/O) as well as electrically couple to a microelectronic chip. One or more photonic chip or optical fiber terminal may be coupled to an optical I/O of the PLC. In embodiments the PLC includes a light modulator, photodetector and coupling regions supporting the optical I/O. Spin-on electro-optic polymer (EOP) may be utilized for the modulator while a photodefinable material is employed for a mode expander in the coupling region.

  • Publication number: 20130272649
    Abstract: Embodiments of the present disclosure provide optical connection techniques and configurations. In one embodiment, an apparatus includes a receptacle for mounting on a surface of a package substrate, the receptacle having a pluggable surface to receive an optical coupler plug such that the optical coupler plug is optically aligned with one or more optical apertures of an optoelectronic assembly that is configured to emit and/or receive light using the one or more optical apertures in a direction that is substantially perpendicular to the surface of the package substrate when the optoelectronic assembly is affixed to the package substrate. Other embodiments may be described and/or claimed.

  • Publication number: 20120251029
    Abstract: Embodiments of the invention describe a multi-segment optical waveguide that enables an optical modulator to be low-power and athermal by decreasing the device length needed for a given waveguide length. Embodiments of the invention describe an optical waveguide that is folded onto itself, and thus includes at least two sections. Thus, embodiments of the invention may decrease the device size of a modulator by at least around a factor of two if the device is folded twofold (device size may be further reduced if the modulator is folded threefold, four-fold, five-fold, etc.). Embodiments of the invention further enable the electrode length required to create the desired electro-optic effect for the multi-segment optical waveguide to be reduced. In embodiments of the invention, certain electrodes may be “shared” amongst the different segments of the waveguide, thereby reducing the power requirement and capacitance of a device having a waveguide of a given length.
