Abstract :
Beam shaping of light on a micron scale is of particular importance when targeting integrated photonic applications. Here, we present a high numerical aperture lens based on high contrast gratings incorporating multiple phase shifts. We show successful fabrication and micron scale focusing which is beneficial to the micro-optics community.
