Stand-Off Biodetection with Free-Space Coupled Asymmetric Microsphere Cavities

Stand-Off Biodetection with Free-Space Coupled Asymmetric Microsphere Cavities

Asymmetric microsphere resonant cavities (ARCs) allow for free-space coupling to high quality (Q) whispering gallery modes (WGMs) while exhibiting highly directional light emission, enabling WGM resonance measurements in the far-field. These remarkable characteristics make “stand-off” biodetection i...
