    摘要: An arrangement for providing passive alignment between an optical fiber and the “tip” of a nanotaper coupling waveguide (the nanotaper formed within the SOI layer of an SO-based optoelectronic arrangement). The arrangement includes a separate fiber carrier support element, including a longitudinal V-groove for supporting the fiber and an alignment feature formed parallel thereto. The SOI structure is formed to include an associated alignment slot, so that as the fiber carrier is positioned over and attached to the SOI structure, the alignment feature and alignment slot will mate together and provide passive alignment of the optical fiber to the nanotaper waveguide tip.

    摘要: An arrangement for removing unwanted amplitude modulation from the output of an electro-optic phase modulator (formed within a silicon-on-insulator (SOI) system) includes resonant filters that are biased on the positive and negative slopes of the response signal. Therefore, as the amplitude response of one filter decreases, the amplitude response of the other filter increases, resulting in balancing the output and essentially eliminating amplitude modulation from the phase-modulated output signal. In one embodiment, ring resonators (formed in the SOI layer) are used to provide the filtering, where as the number of resonators is increased, the performance of the filtering arrangement is improved accordingly.

    摘要: Computer-aided design (CAD) tools are used to perform the integrated design, verification and layout of electrical and optical components in a monolithic, silicon-based electro-optic chip. Separate top-level behavioral logic designs are prepared for the three different types of elements included within the final, silicon-based monolithic structure: (1) digital electronic integrated circuit elements; (2) analog/mixed signal electronic integrated circuit elements; and (3) opto-electronic elements (including passive and active optical elements). Once the behavioral logic design is completed, the results are combined and co-simulated. A physical layout design is developed and verified for each different type of element in the circuit. The separate physical layouts are then co-verified, to assess the properties of the overall physical design. The results of the co-simulation are compared to the results of the co-verification, with alterations made in the logic design and/or the physical layout until the desired operating parameters are obtained. Once the desired results are generated, conventional wafer-level fabrication operations are then considered to provide a final product (“tape out”).

    摘要: An effective index modifier that modifies light propagation in a waveguide. The device is formed on a wafer, such as a Silicon-On-Insulator (SOI) wafer that includes an insulator layer and an upper silicon layer. A waveguide is formed at least in part in the upper silicon layer of the SOI wafer. The waveguide guides an optical signal by total internal reflection. At least one micro-mechanical system (MEMS) having at least one movable component is disposed a positive distance away from the waveguide. Application of voltage to the MEMS results in a variation of the distance between the moveable component and the waveguide, which in turn alters the effective index of the waveguide in a location proximate the moveable object, thereby resulting in modification of light propagation in the waveguide.
