Internet traffic loads are increasing. Sustaining packet switching throughput of a core node will be difficult. A major reason for this is power consumption and packaging volume. As long as we use only current semiconductor technology, the switching capacity will be limited. Rapid single flux quantum (RSFQ) superconducting technology can overcome such difficulties because of high-speed operation and low-power consumption characteristics. A superconducting wiring also enables high-speed inter-chip communication. We report on progress on packet switch circuit implementation and cryo-cooled packaging for a RSFQ packet switch system. In addition, we discuss a possible packet switch architecture over 100 Tbps that uses RSFQ technology.

We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.
