Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CASPeer-Reviewed Publication
Scientists from China have developed high-performance colloidal quantum-dot (CQD) surface-emitting laser array based on circular Bragg resonator (CBR). The CQD CBR laser array, leveraging high-quality CQD material with low gain threshold and high stability and CBR cavity with strong optical confinement, features a low lasing threshold, high pixel density (2100 PPI), and a remarkable 1000-hour operation lifetime (3.63 × 108 pulses) at room temperature, promising advancements for practical CQD laser applications in the future.
