Title: Sensing and timekeeping using a light-trapping diamond waveguide


Solid-state quantum systems have emerged as promising sensing platforms. In particular, the spin properties of nitrogen vacancy (NV) color centers in diamond make them outstanding nanoscale sensors of magnetic fields, electric fields, and temperature under ambient conditions.  I will a describe power-efficient diamond waveguide structure using large ensembles (>10^10) of NVs for sensing with sub-millimeter-scale spatial resolution. The talk will cover challenges of working with large ensembles of defects as well as strategies for combatting sensitivity-limiting ambient temperature fluctuations.  Magnetometry, temperature sensing, and timekeeping applications are explored.
