    摘要： A spotsize converter (200) includes a substrate layer (201); a first coverage layer (202) disposed above the substrate layer (201); an isolating layer (203) disposed between the substrate layer (201) and the first coverage layer (202); and a waveguide (204) disposed inside the first coverage layer (202), where the waveguide (204) is symmetrical along a principal axis. The waveguide (204) includes an equal-width first waveguide (301), an equal-width second waveguide (302), and a third waveguide (303). A first end of the third waveguide (303) is connected to a first end of the first waveguide (301) and a first end of the second waveguide (302), and the first waveguide (301), the second waveguide (302), and the third waveguide (303) form a Y shape. Along a first direction of the principal axis, a width of the third waveguide (303) gradually increases, and a distance, in a second direction, between the first waveguide (301) and the second waveguide (302) gradually decreases. The spotsize converter (200) can be used to implement spot size conversion between an optical fiber and an optical waveguide, and a coupling loss between the optical fiber and the optical waveguide can be reduced by using the spotsize converter (200).

    摘要： A tapered waveguide includes a central waveguide (10) and shallow-etched strip waveguides (20) disposed on both sides of the central waveguide. Each shallow-etched strip waveguide (20) is of a structure with a gradually changing width, and an outline, away from the central waveguide (10) and in a length direction, of the shallow-etched strip waveguide (20) is a concave arc without an abrupt change. An effective refractive index changes slowly and an insertion loss of a device can be effectively reduced. In addition, a wider area of the shallow-etched strip waveguide has a shorter length. In this way, a length of the device is effectively reduced, thereby facilitating miniaturization of the device. A silicon-based chip is further disclosed.

    摘要： Embodiments of the present disclosure are directed toward techniques and configurations for an optical device having a semiconductor layer to propagate light and a mirror disposed inside the semiconductor layer and having echelle grating reflective surface to substantially totally internally reflect the propagating light inputted by one or more input waveguides, to be received by one or more output waveguides. The waveguides may be disposed in the semiconductor layer under a determined angle relative to the mirror reflective surface. The determined angle may be equal to or greater than a total internal reflection angle corresponding to the interface, to provide substantially total internal reflection of light by the mirror. The mirror may be formed by an interface of the semiconductor layer comprising the mirror reflective surface and another medium filling the mirror, such as a dielectric. Other embodiments may be described and/or claimed.

    摘要： Techniques and mechanisms for providing efficient direction of light to a photodetector with a tapered waveguide structure. In an embodiment, a taper structure of a semiconductor device comprises a substantially single crystalline silicon. A buried oxide underlies and adjoins the monocrystalline silicon of the taper structure, and a polycrystalline Si is disposed under the buried oxide. During operation of the semiconductor device light is redirected in the taper structure and received via a first side of a Germanium photodetector. In another embodiment, one or more mirror structures positioned on a far side of the Germanium photodetector may provide for a portion of the light to be reflected back to the Germanium photodetector.
