Nitrogen-Vacancy (NV) color centers in diamond have emerged as promising\nquantum solid-state systems, with applications ranging from quantum information\nprocessing to magnetic sensing. One of the most useful properties of NVs is the\nability to read their ground-state spin projection optically at room\ntemperature. This work provides a theoretical analysis of Purcell enhanced NV\noptical coupling, through which we find optimal parameters for maximal Signal\nto Noise Ratio (SNR) of the optical spin-state readout. We conclude that a\ncombined increase in spontaneous emission (through Purcell enhancement) and in\noptical excitation could significantly increase the readout SNR.\n
