An asynchronous optical token smart-pixel design based on hybrid CMOS-SEED integration

We describe an asynchronous optical token-based arbitration circuit designed and implemented using hybrid CMOS-SEED smart-pixel technology. Our design exploits fast, global communication chip links offered by free-space optics while providing nontrivial logic functionality required by electronic-based network operations. Thus, we show that smart-pixel technology is applicable to multiprocessor interconnection networks.
