Subwavelength-Engineered Metamaterial Devices for Integrated Photonics.

Incorporating subwavelength grating metamaterials in nanophotonic waveguides has opened new degrees of freedom to control light propagation on a photonic chip. In this invited contribution, we will present our recent advances in development of subwavelength-engineered metamaterial devices for silicon photonics, including fiber-chip couplers, nanophotonic waveguides with controlled anisotropy, resonant waveguides, complex spectral filers and nanoantennas for Optical Phased Arrays (OPAs).
