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.
