Abstract: An SOI-based optical interconnection arrangement is provided that significantly reduces the size, complexity and power consumption requires of conventional high density electrical interconnections. In particular, a group of optical modulators and wavelength division multiplexers/demultiplexers are used in association with traditional electrical signal paths to “concentrate” a large number of the electrical-pinouts onto one optical waveguide (e.g., fiber). By utilizing a number of such SOI-based signal concentration structures, an optical backplane can be formed that couples all of these concentration structures through one optical substrate and then onto a separate number of output/receiving boards. Additionally, optical gain material may be embedded within the backplane element to further enhance the optical signal quality.

Abstract: 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.
