    摘要: An optical coupling system and method of fabrication are included. The optical coupling system includes a substrate layer and an optical waveguide material overlying the substrate layer. The optical waveguide material can include a grating. The system also includes a cover material overlying the optical waveguide material to couple an optical signal to the optical waveguide material via the grating at a coupling angle. Approximately zero energy of the coupled optical signal is lost in the substrate layer due to a combination of the coupling angle and a difference in refractive indices between the cover material and the substrate layer.

    摘要: A broadband optical beam splitter can comprise a non-metallic high contrast grating including a substrate and an array of posts attached to a surface of the substrate. The grating can have a subwavelength period with respect to a preselected optical energy wavelength, the preselected optical energy wavelength within the range of 400 nm to 1.6 μm. Additionally, the broadband optical beam splitter can have a bandwidth of 80 nm to 120 nm and can have an optical energy loss of less than 5%.

    摘要: One example relates to an optical engine comprising a given layer of given material overlaying an optical waveguide of another material. The given layer of given material can comprise an aligning seat to receive an optical transmitter to provide the optical signal. The aligning seat can also align the optical transmitter such that the optical transmitter provides the optical signal in a direction that is substantially non-oblique relative to a longitudinal axis of the optical waveguide. The optical engine can also include an optical signal redirector to tilt the optical signal by a tilt angle. The optical waveguide can comprise a grating coupler to diffract the optical signal provided at the tilt angle into the optical waveguide.
