Paper Abstract
We propose a novel vertical optical coupler using subwavelength high contrast grating. The
surface normal incidence light can be coupled into the in-plane waveguide with peak efficiency
of 92% over a broad wavelength range. Such structure can be also designed as the in-plane
reflector or in-plane to vertical coupler. The reflectivity for waveguide propagation mode is 97.5%
and the coupling efficiency is 96%, respectively.
