HIGHLY EFFICIENT BROAD-BAND WAVEGUIDE GRATING COUPLER WITH A SUB-WAVELENGTH GRATING MIRROR
Abstract
A new diffractive device for light coupling between a planar optical waveguide and free space is proposed. The device utilizes a second order waveguide grating to diffract the fundamental waveguide mode into two free propagating beams and a sub-wavelength grating (SWG) mirror to combine the two free propagating beams into a single beam. The Finite Difference Time Domain (FDTD) simulations show that the SWG mirror improves the coupling …
