The eminence of communication costs over computation costs in current systems-on-chip (SoCs) has led to a change in the assumptions and methodology of the deep submicron design process. The emergence of non-traditional global signaling techniques such as optical interconnects, wireless communication, and transmission lines adds further complexity to the design exercise. There is a pressing need...

The bandwidth bottleneck looming for traditional electronic interconnects necessitates the use of optical communications, as realized through the CMOS-compatible silicon nanophotonic platform. Within the silicon photonics platform, silicon microring resonators have received a great deal of attention for their ability to implement the critical functionalities of an on-chip optical network while ...

We report error-free long-haul transmission of optical data modulated using a silicon microring resonator electro-optic modulator with modulation rates up to 12.5 Gb/s. Using bit-error-rate and power penalty characterizations, we evaluate the performance of this device with varying modulation rates, and perform a comparative analysis using a commercial electro-optic modulator. We then experimen...

With the rapid development of on-chip optical interconnects and optical computing in the past decade, silicon-based integrated devices for monolithic and hybrid optoelectronic integration have attracted wide attention. Due to its narrow pseudo-direct gap behavior and compatibility with Si technology, epitaxial Ge-on-Si has become a significant material for optoelectronic device applications. In...

I. Project Summary This project addresses five key elements for future high-performance computing: (1) high-throughput, (2) lowlatency, (3) energy-efficiency, (4) scalability, and (5) high-radix, all-to-all connectivity. Computing and data centers today are dissipating Megawatts of power, and scaling to an exascale system would require nearly a Gigawatt [1]. Amdahl’s law suggests that a system ...

A new CAD tool fREEDA based on state variable approach and universal error concept is presented for modelling and simulating systems where physical domains such as electrical, thermal, and optical interact with each other. A single implementation of device equations in fREEDA can be used with different analysis types such as transient and harmonic balance, etc. To demonstrate the multi-physics ...
