Abstract
The present invention relates to an integrated photonic device () operatively coupleable with an optical element () in a first coupling direction. The integrated photonic device () comprises an integrated photonic waveguide () and a grating coupler () that is adapted for diffracting light from the waveguide () into a second coupling direction different from the first coupling direction. The integrated photonics device also comprises a refractive element () disposed adjacent the grating coupler () and adapted to refract the light emerging from the grating coupler () in the second coupling direction into the first coupling direction.
