High-Rate Cross-Channel Entanglement Swapping Between Independent On-Chip Sources. [PDF]

Adv Sci (Weinh)
To interconnect individual chip‐based quantum sources, high‐performance entanglement swapping is indispensable. Here, using low‐loss silicon chips with waveguide structure and frequency‐offset pumps, this work demonstrates high‐rate cross‐channel entanglement swapping.

Foundry-enabled wafer-scale characterization and modeling of silicon photonic DWDM links. [PDF]

Nanophotonics
Abstract AI/ML compute clusters are driving unprecedented bandwidth demands at the package boundary, motivating co‐packaged integrated photonics closely co‐located with the compute unit. We present a scalable silicon‐photonics transceiver platform and a measurement‐driven design methodology that together enable dense, energy‐efficient DWDM links ...

Rapid adiabatic couplers with arbitrary split ratios for broadband DWDM interleaver application. [PDF]

Nanophotonics
Abstract We experimentally demonstrate compact and broadband rapid adiabatic couplers (RACs) with arbitrary power split ratios, achieved through the combination of translational offset and waveguide width control. Fabricated RACs of four different target split ratios show power splitting within ±3 % of the design target over a 160 nm wavelength range ...

Robust transport of high-speed data in a topological valley Hall insulator. [PDF]

Nanophotonics
Abstract Photonic topological insulators provide robust transport of light, enabling interesting phenomena such as unidirectional light propagation and immunity to disorder. The discovery of how to effectively break time reversal symmetry was an important development in the field of photonic topological insulators. Knowledge on how to implement designs
