Journal ArticleDOI
Photonic Networks-on-Chip for Future Generations of Chip Multiprocessors
TL;DR: Results confirm the unique benefits for future generations of CMPs that can be achieved by bringing optics into the chip in the form of photonic NoCs, as well as a comparative power analysis of a photonic versus an electronic NoC.
Journal ArticleDOI
Characterization of photodamage to Escherichia coli in optical traps.
TL;DR: A wavelength-tunable optical trap was employed in which the microscope objective transmission was fully characterized throughout the near infrared, in conjunction with a sensitive, rotating bacterial cell assay, and the intensity dependence for photodamage was linear, supporting a single-photon process.
Journal ArticleDOI
Optical 4x4 hitless slicon router for optical networks-on-chip (NoC).
Nicolás Sherwood-Droz,Howard Wang,Long Chen,Benjamin G. Lee,Aleksandr Biberman,Keren Bergman,Michal Lipson +6 more
TL;DR: A spatially non-blocking optical 4x4 router with a footprint of 0.07 mm(2) for use in future integrated photonic interconnection networks and successfully routed a single-wavelength laser.
Journal ArticleDOI
Recent advances in optical technologies for data centers: a review
TL;DR: This review paper analyzes optical technologies that will enable next-generation data center optical interconnects to address the challenges of terabit/s links and networks at the laser, modulator, photodiode, and switch levels.
Proceedings ArticleDOI
On the Design of a Photonic Network-on-Chip
TL;DR: Simulations show that this class of photonic networks-on-chip offers a significant leap in the performance for CMP intrachip communication systems delivering low-latencies and ultra-high throughputs per core while consuming minimal power.
