Abstract:
An extensible framework is proposed for on-chip spatial-mode manipulations based on metamaterial building blocks, which enables the excitation of arbitrarily high-order spatial modes in silicon waveguides. It makes a significant step towards the comprehensive and on-chip manipulations of spatial lights, and may provide promising opportunities for complex photonic functionalities.
