—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)
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)
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)
The effects of a micrometer-scale silicon ring resonator with a FWHM of 0.078 nm (9.6 GHz) on a nonreturn to zero amplitude-modulated optical signal with a modulation rate of 10 Gbps are experimentally investigated. By transmitting the optical signal through the device, significant spectral distortion and side band attenuation is introduced, as(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)
—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)
—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)
