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 ...
