Corona: System Implications of Emerging Nanophotonic Technology
This work believes that in comparison with an electrically-connected many-core alternative that uses the same on-stack interconnect power, Corona can provide 2 to 6 times more performance on many memory intensive workloads, while simultaneously reducing power.
Devices and architectures for photonic chip-scale integration
This paper presents a design study for a many-core architecture called Corona which utilizes dense wavelength division multiplexing (DWDM) for on- and off-chip communication together with the devices which will be needed to implement such a communication infrastructure.
Silicon microring resonators with 1.5-μm radius
We demonstrate a junction between a silicon strip waveguide and an ultra-compact silicon microring resonator that minimizes spurious light scattering and increases the critical dimensions of the
Nanoelectronic and Nanophotonic Interconnect
It is shown that there is in principle a four order of magnitude bandwidth-to-power ratio advantage for the photonic interconnect, which indicates that it could be possible to dramatically improve chip performance without scaling transistors but rather utilize the capability of existing transistors much more efficiently.
Resonant enhancement of the zero-phonon emission from a colour centre in a diamond cavity
Integrated quantum photonic technologies are key for future applications in quantum information, ultralow-power opto-electronics and sensing. As individual quantum bits, nitrogen-vacancy centres in
Coupling of nitrogen-vacancy centers to photonic crystal cavities in monocrystalline diamond.
The zero-phonon transition rate of a nitrogen-vacancy center is enhanced by a factor of ∼70 by coupling to a photonic crystal resonator fabricated in monocrystalline diamond using standard
Observation of the dynamic Jahn-Teller effect in the excited states of nitrogen-vacancy centers in diamond.
The optical transition linewidth and emission polarization of single nitrogen-vacancy centers are measured and it is found that the dynamic Jahn-Teller effect is the dominant dephasing mechanism for the NV optical transitions at low temperatures.
Setting upper limits on the strength of periodic gravitational waves from PSR J1939+2134 using the first science data from the GEO 600 and LIGO detectors
Data collected by the GEO 600 and LIGO interferometric gravitational wave detectors during their first observational science run were searched for continuous gravitational waves from the pulsar
Flat dielectric grating reflectors with focusing abilities
Sub-wavelength dielectric gratings have emerged recently as a promising alternative to distributed Bragg reflection dielectric stacks for broadband, high-reflectivity filtering applications. Such a
Silicon waveguide with four zero-dispersion wavelengths and its application in on-chip octave-spanning supercontinuum generation.
We propose a novel silicon waveguide that exhibits four zero-dispersion wavelengths for the first time, to the best of our knowledge, with a flattened dispersion over a 670-nm bandwidth. This holds a
