Optically active defects in diamond find a wide range of applications from lasers to single photon emitters essential for quantum communications. Ion implantation followed by thermal annealing is a mature technique used to create such defects. Implanted at a fixed energy, ions form a thin layer of optically active defects. Low temperature photoluminescence spectra of Xe‐related defects in pure CVD...
The persistent spectral hole-burning (PSHB) phenomenon observed in molecular doped polymers cooled down to liquid helium temperatures allows the engraving of spectral structures in the inhomogeneous absorption profile of the material. Therefore, a PSHB molecular-doped solid can be programmed in the spectral domain and then converted in an optical processor capable to achieve user-defined optical functions...
