Miniature fiber facet atomic force microscope using photonic crystal sensors

A miniaturized Atomic Force Microscope is fabricated on the facet of an optical fiber. Photonic crystal mirrors are integrated into the fabrication creating a Fabry Perot sensor for sensitive force measurements that verify the probe´s ability to resolve forces down to 8 pN/Hz^0.5. This AFM form factor enables a path towards in-vivo, high-bandwidth and non-contact AFM imaging.
