    摘要： Embodiments of the present disclosure describe techniques and configurations for decreasing optical loss in a wave-guide of a modulator device. In one embodiment, an apparatus includes a substrate, and a waveguide of a modulator device formed on the substrate, the waveguide having a first portion that is configured to receive light for propagation along the waveguide, a second portion that includes two slots formed in the waveguide that merge into a single slot, the second portion being coupled with the first portion, a third portion that includes the single slot formed in the waveguide, the third portion being coupled with the second portion, a fourth portion that includes another two slots formed in the waveguide, the another two slots branching from the single slot, the fourth portion being coupled with the third portion, and a fifth portion that is configured to output the propagated light, the fifth portion being coupled with the fourth portion. Other embodiments may be described and/or claimed.

    摘要： Systems and methods may couple on-chip optical circuits to external fibers. An SOI waveguide structure may include mirror structures and tapered waveguides to optically couple optical circuits to fibers in a vertically oriented external connector. The mirror structure(s) may be angularly disposed at the ends of the silicon waveguide structure. An oxide layer may cover a buried oxide layer and the silicon waveguide structure. The tapered waveguide(s) may have a narrow end and a wide end. The narrow end of the tapered waveguide(s) may be disposed above the mirror structures. The tapered waveguide(s) may extend through the oxide layer from the narrow end in a direction perpendicular to the silicon waveguide structure. An external connector may fit over the tapered waveguide(s) and uses a fiber array traveling through a connector body to optically couple to the external fiber.

    摘要： 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.
