Diamond nanophotonic structures hold immense potential for breakthroughs in quantum infomations technologies and are a leading platform for developing quantum memory chips.
One challenge in the development of nanophotonic structures lies in the reliable transfer and bonding of single crystal diamond thin-films onto suitable substrates.
Here we present an innovative and scalable method that utilizes a sol-gel process, which holds promise for efficiently and securely managing the transfer of these thin-film diamonds.
This method can elevate the fabrication of nanophotonic structures on diamonds, which can serve as interfaces between the spins of color centers, such as SiV, and photons.
Thus, it contributes to a new possibility for integrating such structures into photonic networks, promising significant advances in quantum optics and communication.
