Surface-emitting lasers meet metasurfacesOA北大核心CSTPCD

The integration between vertical-cavity surface-emitting lasers and metasurfaces has been demonstrated to enable on-chip high-angle illumination for total internal reflection and dark-field microscopy.Such an ultracompact combined laser-beam shaper system provides a versatile illumination module for high-contrast imaging,thus leveraging biophotonics and lab-on-a-chip devices and facilitating life-science applications.
