EE385b Seminar http://arith.stanford.edu/ee385b_sched.spr97.html Title: Introduction to Switching Architectures for All Optical Networks Speaker: Hyuk-Jun Lee, CSL, hyukjunl@arith.stanford.edu Date: April 30, 1997, 12:15 (noon) Place: CS Building, Gates B08. Abstract: The rapidly increasing data traffic in telecommunication networks requires new switching architectures. The realization of high bandwidth switches (>Tbbs = greater than Tera-bits-per-seconds) using electronics only, introduces problems such as poor scalability, large power consumtion, etc. The maturing of photonic technology suggests ALL OPTICAL datapath based network switching as a promising alternative to overcome these problems. In this talk, the photonic devices that have been developed by several groups, including Multiple Quantum Well X-Modulators (Stanford) and the Sagnac Loop Gate (MIT/AT&T) will be introduced. The construction of space-time switches using these devices will be discussed, as well as the unique use of group theory and shuffle algebra. Various issues will be covered, including: efficiency-simplicity tradeoffs of switch control algorithms, hardware complexity, integratability, and photonic technology.
