- Summary:
- Single-mode, high-power optical beam generation is essential for a wide range of applications, such as light detection and ranging (LiDAR), industrial heating systems and broad-area displays. The development of microlasers over the past two decades, facilitating properties including small footprint and high-power efficiency, opens the new field of integrated photonics and offers us a solution to on-chip laser arrays. However, the wave nature of light leads to fundamentally inevitable mutual coupling between photonic elements closely packed in a microlaser array. Control of mutual coupling is therefore the key to phase-locking of all the lasing elements and further driving them to operate collectively. To solve this problem, Quantum Mechanics (QM)-inspired photonics was studied, and several different approaches were proposed and experimentally demonstrated, such as Parity-Time (PT) microlasers and Supersymmetric (SUSY) microlaser arrays. In addition, a microlaser array, driven by non-Hermitian gauge theory, featuring single-mode lasing where all lasing elements function coherently is proposed and experimentally demonstrated.
