Abstract

Micro- and nano-disk lasers have emerged as promising optical sources and probes for on-chip and free-space applications. However, the randomness in disk diameter introduced by standard nanofabrication makes it challenging to obtain deterministic wavelengths. To address this, we developed a photoelectrochemical (PEC) etching-based technique that enables us to precisely tune the lasing wavelength with sub-nanometer accuracy. We examined the PEC mechanism and compound semiconductor etching rate in diluted sulfuric acid solution. Using this technique, we produced microlasers on a chip and isolated particles with distinct lasing wavelengths. Our results demonstrate that this scalable technique can be used to produce groups of lasers with precise emission wavelengths for various nanophotonic and biomedical applications.

半导体微盘激光器的精确光电化学调谐

微型和纳米盘激光器已成为芯片上和自由空间应用的有前途的光源和探针。然而，标准纳米制造引入的圆盘直径的随机性使得获得确定性波长具有挑战性。为了解决这一问题，我们开发了一种基于光电化学（PEC）蚀刻的技术，使我们能够以亚纳米级的精度精确调谐激光波长。我们研究了PEC机制和化合物半导体在稀硫酸溶液中的蚀刻速率。利用这项技术，我们在芯片上制造了微型激光器，并分离出具有不同激光波长的粒子。这些精确调谐的圆盘激光器随后被用于标记培养中的细胞。我们的研究结果表明，这种可扩展的技术可以用于生产具有精确发射波长的激光器组，用于各种纳米光子和生物医学应用。
