Etchless Dion–Jacobson-phase perovskite surface-emitting circular Bragg lasers with an ultrahigh Q factor
We developed an etchless fabrication method for Dion–Jacobson-phase perovskite active photonics and demonstrated surface-emitting circular Bragg lasers, achieving a low lasing threshold of 8 μJ/cm 2 and a record-high quality factor of ~1.2 × 10 4 .
