    摘要: In an embodiment of the invention, an optical coupler couples light unidirectionally from integrated circuit package to an integrated circuit die. The package has a large waveguide with a waveguide core that has a low index of refraction. The die has a set of very small waveguide cores that have a high index of refraction relative to the index of refraction of the large waveguide core on the package. The waveguide cores with high index of refraction attract light from the waveguide core with the low index of refraction. No light is coupled back into the large waveguide core. Also, the optical mode of the large waveguide on the package is smaller than a subset of waveguide cores on the die. Thus, light is coupled from the package to the die without the waveguide cores having to be tightly aligned with each other.

    摘要: In an embodiment, light from a single mode light source may be deflected into a low index contrast (LIC) waveguide in an opto-electronic integrated circuit (OEIC) (or “opto-electronic chip”) by a 45 degree mirror. The mirror may be formed by polishing an edge of the die at a 45 degree angle and coating the polished edge with a metal layer. Light coupled into the LIC waveguide may then be transferred from the LIC waveguide to a high index contrast (HIC) waveguide by evanescent coupling.

    摘要: A waveguide includes a waveguide core that has a bottom surface and a top surface that defines an angle. The waveguide also includes a cladding layer adjacent to the bottom surface. The cladding layer has a thickness equal to or greater than an evanescent tail of a mode to be transmitted along the wave guide core.
