Rapidly reconfigurable radio-frequency arbitrary waveforms synthesized on a CMOS photonic chip
Jian Wang, Hao Shen, Li Fan +9
Photonic methods of radio-frequency waveform generation and processing provide performance and flexibility over electronic methods due to the ultrawide bandwidth offered by the opt…
A CMOS compatible microring-based on-chip isolator with 18dB optical isolation
Li Fan, Jian Wang, Hao Shen +4
We demonstrate strong optical nonreciprocity in microring add-drop filters with asymmetric input and output coupling coefficients. Up to 18dB isolation was achieved with a silicon-…
Eight-channel reconfigurable microring filters with tunable frequency, extinction ratio and bandwidth
Hao Shen, Maroof H. Khan, Li Fan +5
We demonstrate an eight-channel reconfigurable optical filter on a silicon chip consisting of cascaded microring resonators and integrated compact heaters. With an embedded Mach-Ze…
New Constraints from PAMELA anti-proton data on Annihilating and Decaying Dark Matter
Ilias Cholis
Recently the PAMELA experiment has released its updated anti-proton flux and anti-proton to proton flux ratio data up to energies of ~200GeV. With no clear excess of cosmic ray ant…
