SILICON PHOTONICS FOR NEXT GENERATION COMPUTING SYSTEMS (TUTORIAL)
Vlasov, Yurii
The current tendency in high performance computing systems is to increase the parallelism in processing at all levels utilizing multithreads, increasing the number of chips in racks and blades, as well as increasing the number of cores on a chip. The scaling of overall system performance that soon might approach Exaflop/s is, however, out of balance with respect to limited available bandwidth for shuttling ExaBytes of data across the system, between the racks, chips and cores. We will discuss how optics can provide huge power and bandwidth benefits closer and closer to the chip and eventually into the chip itself that would allow to overcome severe constraints of today’s mostly copper I/O interconnects. Particular emphasis will be given to silicon photonics integrated circuits designed for low power off-chip and on-chip optical networks. |

MULTI-FUNCTION INTEGRATED INP-BASED PHOTONIC CIRCUITS (TUTORIAL)
Coldren, Larry
Although InP-based photonic ICs (PICs) have been researched for many years, widespread acceptance of the viability of such technologies has not occurred until recently. A few relatively new commercial existence proofs have now proven that multiple functions can be successfully performed on a single InP chip with advantages in cost, size, performance, and power dissipation. As a result of these, as well as some market realities and an ever growing body of research existence proofs, the development of viable PIC products now seems to be a key goal of many component suppliers. This tutorial will review current integration approaches and results, with some slight emphasis on our UCSB work. |
