Deterministic Integration of Quantum Emitters and Optical Cavities in a Van Der Waals Crystal
Advanced Optical Materials, EarlyView.The work demonstrates fabrication of Circular Bragg Grating (CBG) cavities with embedded emitters in hBN. The cavities are fabricated around a pre‐characterised quantum emitter. The integrated platform enables light matter interaction and access to brighter emitters and spins in hBN.

Phonon Polariton Confinement in Isotopically Pure MOVPE‐Grown BN Triangles
Advanced Optical Materials, EarlyView.Phonon polaritons are confined in MOVPE‐grown isotopically pure 10BN$^{10}{\rm BN}$ triangles. The resonator modes are excited and mapped by near‐field spectroscopy. Through scanning a wide infrared frequency range and modeling, the polariton dispersion relation is retrieved.
