Abstract
Section titled âAbstractâAbstract Color centers, optically active defects within solids, are vital for leading quantum information technologies such as quantum computing and quantum sensing. An essential prerequisite for realizing scalable quantum architectures is the ability to create quantum emitters deterministically. In the last decades, significant efforts have been devoted to selectively generating color centers. One of the most used methods is highâenergy ion implantation. However, this method usually causes extended lattice damage along the entire trajectory because of ions bombardment. Moreover, the position depth of color centers is also limited by the ions penetrate length in crystals. The direct laserâwriting (DLW) technique has recently emerged as a powerful tool to create color centers in solidâstate materials. It can define color centers at arbitrary depths inside the substrate and operate at the ambient environment, therefore, providing a feasible 3D fabrication method for integrated quantum photonics. Here, recent advancements of laser writing of color centers in solidâstate materials are reviewed, from bulk crystals, such as diamond and silicon carbide, to nanostructures, involving singleâwalled carbon nanotubes, 2D layered materials, and quantum dots.
