Optical interconnect technology for multiprocessor networks

Networks for connecting processors to each other will require Gigabit/sec data rate; high speed setup; dense packaging, comparable to VLSI electronics; robustness, in terms of reliable components, low link bit-error-rate, and easy reconfigurability; and low cost. A GaAs based OEIC chip with all link adapter functions on one chip, a multichip carrier with self-aligned optics and opto-electronics, and multimode fiber arrays cable and connectors are optical technology elements that could be developed in the near term to provide such a multiprocessor network technology. However, component and link development work is still required to verify the technology's potential for reliability, volume manufacturability, and low cost.
