Nanolasers: towards large-scale phase-locked laser arrays

Nanolasers have been extensively studied as promising on-chip light sources in the past two decades due to their ultra-small footprint, high energy efficiency and fast modulation speed, that are advantageous for various applications, including imaging, sensing, and neuromorphic circuits. This invited paper introduces the development of the metallo-dielectric nanolasers (MDNLs) designed at UCSD towards their applicability in large-scale laser arrays, ranging from their design and demonstration to the recent on-going work on the demonstration of phase-locking of bridge-coupled nanolasers.
