New Paper: Vapor Phase Assembly of Molecular Emitter Crystals for Photonic Integrated Circuits

We are excited to share our latest preprint on the vapor-phase assembly of molecular emitter crystals for photonic integrated circuits. In this work, we demonstrate a scalable method for growing optically thin, high emitter density anthracene crystals doped with dibenzoterrylene (DBT) molecules directly onto photonic chips. This approach enables the deterministic integration of quantum emitters with nanophotonic structures, a key step toward building practical quantum photonic devices.
