Single-mode, widely tunable semiconductor lasers are essential for coherent communications, precision sensing, and reconfigurable photonic systems. Yet many existing approaches rely on regrowth, etched gratings, or other fabrication-intensive strategies that increase complexity and constrain scalability. In their new Optica paper, “ Mode control and dynamic population gratings in quantum-dot lasers,” researchers from KAUST’s Integrated Photonics Lab demonstrate an alternative mode-control mechanism that does not depend on such complex fabrication steps. The key idea is to exploit dynamic
