Experimental study demonstrates on-chip high-angle illumination using integrated surface-emitting lasers and metasurfaces, highlighting applications in portable high-contrast biomedical imaging.
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.
