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.).

Claims 12 and 13:


12. The system of claim 7, wherein the optically-active material of the multi-segment optical waveguide comprises an electro-optical polymer (EOP), ferroelectric oxide, a piezoelectric material, a III-V electro-absorption material, or a Germanium electro-absorption material.



13. A system comprising:
a processor; a memory; and an integrated circuit (IC), the IC and at least one of the processor and the memory to exchange data via a chip-to-chip optical interface, the chip-to-chip optical interface to include a modulator comprising a plurality of electrodes including a first electrode, a second electrode complementary to the first electrode, and a third electrode complimentary to the second electrode, each of the plurality of electrodes aligned relatively parallel to each other, and a multi-segment optical waveguide including optically active material and comprising a first segment positioned between the first and second electrodes, and a second segment positioned between the second and third electrodes, the refractive index of the optically active material of the first segment to change based on an electrical difference applied to the first and second electrodes, and the refractive index of the optically active material of the second segment to change based on an electrical difference applied to the second and third electrodes...
