| dc.description.abstract | Nitrogen-vacancy centers in diamond are promising candidates for a wide range of applications due to their quantum sensing capabilities at room temperature and easy optical readout and manipulation by means of confocal microscopy and the application of microwave radiation. Applying microwave radiation is not a trivial task depending on the application. If a single NV center is addressed, then a thin (20 —m diameter) copper wire is sufficient if the NV is within 50 —m from the wire. However in a large area with a lot of NV centers that must be addressed simultaneously with a homogeneous microwave intensity, then a more specialized microwave antenna is required. Towards this goal, a complete procedure for developing microstrip antennas for NV centers applications is presented. In order to drive all NV centers that point along a given direction with the same intensity, an antenna with a uniform intensity over this area is needed, which is not a trivial task. At a given power, there is a compromise between a uniform intensity and high intensity. This procedure includes the antenna design using optical lithography in order to achieve the desired spatial resolution, fabrication and testing using a vector network analyzer and different diamond samples. The fabricated antennas reached a maximum transmission of around 40% near the desired frequency (2.87 GHz), a 100 MHz bandwidth and are capable of resolving electronic spin resonance with a maximum contrast of 22%. | |
