“…For instance, Purcell enhancement of spontaneous emission rates for SPEs in GaAsN (related to individual nitrogen luminescence centers) was achieved by fabrication of 2D crystal slabs, resulting in a Purcell factor of 6.3. [ 240 ] Color centers in 2D h ‐BN have been coupled to an optical fiber, yielding 10% coupling efficiencies and exemplifying a fully fiber integrated system. [ 241 ] Furthermore, emitters hosted by h ‐BN have been successfully coupled to cavities [ 242 ] and Purcell enhancement was shown for emitters in WSe 2 with a factor of ∼16, [ 243 ] heralding a new era in quantum photonics with 2D materials.…”

Point defects in semiconductors are emerging as an important contender platform for quantum technology (QT) applications, showing potential for quantum computing, communication, and sensing. Indeed, point defects have been employed as nuclear spins for nanoscale sensing and memory in quantum registers, localized electron spins for quantum bits, and emitters of single photons in quantum communication and cryptography. However, to utilize point defects in semiconductors as single-photon sources for QT, control over the influence of the surrounding environment on the emission process must be first established. Recent works have revealed strong manipulation of emission energies and intensities via coupling of point defect wavefunctions to external factors such as electric fields, strain and photonic devices. This review presents the state-of-the-art on manipulation, tuning, and control of single-photon emission from point defects focusing on two leading semiconductor materials-diamond and silicon carbide.

“…Then, the enhancement of the LDOS, thanks to the structured photonic environment, accelerates the spontaneous transition rates of the quantum emitter. The SE rate enhancement is of great interest to diverse applications, including quantum source emission engineering [4][5][6], ultra-brighter optoelectronic devices [7][8][9][10], enhanced light-matter interaction for fluorescence spectroscopy [11][12][13], and single-photon sources (SPSs) [14][15][16].…”

We exploit InSb’s magnetic-induced optical properties to design THz sub-wavelength antennas that actively tune the radiative decay rates of dipole emitters at their proximity. The proposed designs include a spherical InSb antenna and a cylindrical Si-InSb hybrid antenna that demonstrate distinct behaviors. The former dramatically enhances both radiative and non-radiative decay rates in the epsilon-near-zero region due to the dominant contribution of the Zeeman splitting electric octupole mode. The latter realizes significant radiative decay rate enhancement via magnetic octupole mode, mitigating the quenching process and accelerating the photon production rate. A deep learning-based optimization of emitter positioning further enhances the quantum efficiency of the proposed hybrid system. These novel mechanisms are promising for tunable THz single-photon sources in integrated quantum networks.
