Long-Working-Distance Grating Coupler for Integrated Optical Devices
A novel grating coupler design is presented with its experimental demonstration. The grating can focus the outcoming light upward without the need for a lens or additional fabrication steps. The lenslike effect is introduced by applying a deformation to the grating stripes in order to add a phase ma...
