Interconnect-Free Multibit Arithmetic and Logic Unit in a Single Reconfigurable 3 μm2 Plasmonic Cavity

“…First, further Boolean generalization towards complex gates and ALU is a nontrivial task for which the latest inverse design tools can be advantageously applied. 43,44 Second, progress in light source integration by embedding single photons sources, [45][46][47][48][49][50] or by tunnel current-driven emission, [51][52][53] will enable integrating our planar 2D Boolean devices with laserfree on-chip optical excitation and ultimately to plasmon-based quantum technologies. 54…”

“…Bringing the proof-of-concept of modal plasmonic gates and ALU demonstrated here into a future practical implementation will benefit from two recent advances. First, further Boolean generalization toward complex gates and ALU is a nontrivial task for which the latest inverse design tools can be advantageously applied. , Second, progress in light source integration by embedding single photons sources − or by tunnel current-driven emission − will enable integrating our planar 2D Boolean devices with laser-free on-chip optical excitation and ultimately to plasmon-based quantum technologies …”

Tailoring Wavelength- and Emitter-Orientation-Dependent Propagation of Single Photons in Silicon Nanowires

“…To exclude effects due to the specific orientation of the transition dipoles associated to each NV, we only select NV-SiNW systems which host a number between 3 < NV < 10. In case a ND contains 3 or more independent emitters, these NVs can be approximated as scalar quantum emitters (see the supporting information) [32][33][34]. Having no experimental control on the NV emitter orientation, the simplification to a scalar quantum emitter is necessary in the following to allow a direct quantitative comparison of the different coupled ND-SiNW systems.…”

“…This effect, occurring at λ 0 = 800 nm too with the TE 00 and TE 01 modes, might explain the variations in intensity observed as a function of W . We want to emphasize here that the propagation lengths in silicon nanowires significantly surpass the propagation lengths of plasmonic single photon waveguides [11,34].…”

Large-scale controlled coupling of single-photon emitters to high-index dielectric nanoantennas by AFM nanoxerography

“…40 Because such emitters can be employed in quantum experiments, research on these singlephoton emitters has increased a lot. [41][42][43][44][45][46][47] As a proof of principle, the nanoantennas used in this study are dimers made of symmetric, rectangular, and single-crystal silicon blocks. This very simple antenna configuration has been abundantly used to demonstrate the Purcell effect with different types of emitters or antenna materials.…”
