We report beaming and enhanced transmission of electromagnetic waves by use of surface corrugated photonic crystals. The modes of a finite-size photonic crystal composed of dielectric rods in free space have been analyzed by the plane-wave expansion method. We show the existence of surface propagating modes when the surface of the finite-size photonic crystal is corrugated. We theoretically and...

We designed an on-chip transformative optic system with a broadband metalens coupler on foundry compatible silicon photonic platform. By adjusting the metalens’ focusing length and mode dimension, insertion loss between crystal waveguide (PhC WG) structures is reduced to 2 dB by matching focal plane PhC WG mode. Alternatively, integrated allow for direct coupling from multi-mode cavity. The on-...
