(3+1)D-printed adiabatic 1-to-N broadband couplers
Adrià Grabulosa, Xavier Porte, Erik Jung +3
We report single-mode 3D optical couplers leveraging adiabatic power transfer towards up to 4 output ports. We use the CMOS compatible additive (3+1)D \emph{flash}-TPP printing for…

Combining one and two photon polymerization for accelerated high performance (3+1)D photonic integration
Adria Grabulosa, Johnny Moughames, Xavier Porte +1
Dense and efficient circuits with component sizes approaching the physical limit is the hallmark of high performance integration. However, current fabrication technology is mostly…
