The Network-on-Chip (NoC) paradigm has emerged as a promising solution for providing connectivity among the increasing number of cores that get integrated into both systems-on-chip (SoC) and chip multiprocessors (CMP). In future high-performance CMPs, however, the high bandwidth requirements will not be adequately provided by electronic NoCs without(More)
—Simultaneous all-optical switching of 20 continuous-wave wavelength channels is achieved in a microring resonator-based silicon broadband 1 2 2 comb switch. Moreover, single-channel power penalty measurements are performed during active operation of the switch at both the through and the drop output ports. A statistical characterization of the drop-port(More)
We demonstrate here a spatially non-blocking optical 4x4 router with a footprint of 0.07 mm 2 for use in future integrated photonic interconnection networks. The device is dynamically switched using thermo-optically tuned silicon microring resonators with a wavelength shift to power ratio of 0.25nm/mW. The design can route four optical inputs to four(More)
As multiprocessors scale to unprecedented numbers of cores in order to sustain performance growth, it is vital that these gains are not nullified by high energy consumption from inter-core communication. With recent advances in 3D Integration CMOS technology, the possibility for realizing hybrid photonic-electronic networks-on-chip warrants investigating(More)
—A 4 2 4 Gb/s microring modulator cascade, which can directly convert data from a parallel electrical bus to a multiple-wavelength optical signal in a single silicon-on-insulator waveguide, is demonstrated and characterized. The integrity of the modulated optical signal is verified using Q-factor extrapola-tions. In addition, the frequency characteristics(More)
Most demonstrations in silicon photonics are done with single devices that are targeted for use in future systems. One of the costs of operating multiple devices concurrently on a chip in a system application is the power needed to properly space resonant device frequencies on a system's frequency grid. We asses this power requirement by quantifying the(More)
—A nonblocking four-port bidirectional multiwave-length message router for use in photonic network-on-chip (NoC) architectures implementing two-dimensional mesh or torus topolo-gies is fully characterized with bit-error-rate measurements and eye diagrams using three wavelength-parallel 10-Gb/s channels. The experiments demonstrate the feasibility of using(More)
—We present ultra-broadband wavelength conversion in silicon photonic waveguides at a data rate of 40 Gb/s. The dispersion-engineered device demonstrates a conversion band-width spanning the entire- ,-, and-bands of the ITU grid. Using a continuous-wave-band pump, an input signal of wavelength 1513.7 nm is up-converted across nearly 50 nm at a data rate of(More)
