A structured view of the molecule-first quantum-photonics problem: synthesizing coherent DBT:anthracene crystals, positioning them on SiN nanophotonic cavities, and using cavity-QED physics to create tunable single- and multi-emitter systems.
The narrative is now anchored to the vapor-phase crystal work and molecular-defect cavity-QED platform.
The materials thread is built around optically thin DBT:anthracene crystals grown for direct photonic integration. The target morphology is a flat, roughly 200 nm-thick crystal with sub-nanometer roughness, controllable lateral size, and high enough emitter density to place molecules in the near field of a nanophotonic mode.
The spectroscopy thread focuses on narrow, stable zero-phonon-line transitions from DBT in anthracene at cryogenic temperature. The important metrics are linewidth, spectral wandering, inhomogeneous broadening, saturation behavior, lifetime, and whether the crystal remains coherent after becoming thin enough for nanophotonic coupling.
The integration thread decouples emitter synthesis from nanofabrication: grow the molecular crystal separately, then position it onto a pre-fabricated photonic device. This keeps the optical quality of the nanophotonic structure while using the known DBT insertion geometry in anthracene to align the molecular dipole to the cavity electric field.
The cavity-QED thread studies molecular antiresonances, Purcell enhancement, β-factor, cooperativity, and input-output lineshapes in chip-scale photonic crystal cavities. The scientific point is not just brighter emission, but a measurable emitter-cavity system with extracted parameters such as g, κ, γ, C, and Γ1D.
The collective-emitter thread uses light-induced frequency shifts in DBT:anthracene to bring distinct molecules into resonance within a shared cavity mode. That enables dissipative and dispersive molecule-molecule interactions through the cavity, creating a path from single-emitter coupling toward many-body molecular cavity QED.
The workflow combines FDTD, GDS generation, cleanroom processing, AFM/SEM/metrology, cryogenic spectroscopy, and cavity-QED fitting. The same scientific metric should remain visible from simulation and mask layout to final linewidth, transmission, lifetime, and collection measurements.
