Wavefront Shaping Guided by Optically Detectable Magnetic Resonance

The nitrogen-vacancy (NV) center in diamond is one of the leading platforms for advanced quantum metrology. For the last decade, it has been shown that NV-diamonds detect magnetic fields with exceptional sensitivity and nanoscale spatial resolution. Here, we apply the outstanding sensing abilities of NV centers to adaptive optics in microscopy. We develop a new technique in which optically detectable magnetic resonance (ODMR) guides adaptive wavefront shaping. Our method, in particular, enables far-field control of subwavelength light inside of a multimode nanophotonic device. We experimentally demonstrate our proposal by optically addressing individual spin ensembles below the diffraction limit of microscopy. Our technique will open up a range of new applications including super-depth super-resolution imaging and quantum sensing.
