......Multicore chips are entering commercial and consumer markets at a ferocious pace. They began in special-purpose, niche markets such as high-performance graphics and networking; examples are the eight-core IBM-Sony-Toshiba Cell processor, the 128core Nvidia GeForce 8800 GPU, and the 188-core Cisco Silicon Packet Processor in the CRS-1 router. Recently, multicore chips have been introduced ...

Silicon photonics has generated an increasing interest in recent years mainly for optical communications optical interconnects in microelectronic circuits or bio-sensing applications. The development of elementary passive and active components (including detectors and modulators), which are mainly fabricated on the silicon on insulator platform for CMOS-compatible fabrication, has reached such ...

The ultrafast conversion of electrical signals to optical signals at the nanoscale is of fundamental interest for data processing, telecommunication and optical interconnects. However, the modulation bandwidths of semiconductor light-emitting diodes are limited by the spontaneous recombination rate of electron-hole pairs, and the footprint of electrically driven ultrafast lasers is too large fo...

The primary focus of this review article mainly emphasizes the light absorption enhancement for various nanostructured gratings assisted metal-semiconductor-metal photodetectors (MSM-PDs) that are so far proposed and developed improvement capturing performance. MSM-PDs considered as one key elements in optical high-speed communication systems applications such faster fiber systems, sensor netwo...

Manycore chips are emerging as the architecture of choice to provide power-scalability and improve performance while riding the Moore’s law. On-chip interconnects are increasingly playing a pivotal role in powerand performancescalability of such microarchitectures. As supply voltages begin to level off in future technologies, chip designs in general and interconnects in particular are resorting...

The effect of crosstalk errors is most significant in highperformance circuits, mandating at-speed testing for crosstalk defects. This paper describes a self-test methodology that we have developed to enable on-chip at-speed testing of crosstalk defects in System-on-Chip interconnects. The self-test methodology is based on the Maximal Aggressor Fault Model [13], that enables testing of the inte...

Highly sensitive and fast photodetectors can enable low power, high bandwidth on-chip optical interconnects for silicon integrated electronics. III-V compound semiconductor direct-bandgap materials with high absorption coefficients are particularly promising for photodetection in energy-efficient optical links because of the potential to scale down the absorber size, and the resulting capacitan...
