摘      要：Micro-and nanodisk lasers have emerged as promising optical sources and probes for on-chip and free-space ***,the randomness in disk diameter introduced by standard nanofabrication makes it challenging to obtain deterministic *** address this,we developed a photoelectrochemical(PEC)etching-based technique that enables us to precisely tune the lasing wavelength with subnanometer *** examined the PEC mechanism and compound semiconductor etching rate in diluted sulfuric acid *** this technique,we produced microlasers on a chip and isolated particles with distinct lasing *** precisely tuned disk lasers were then used to tag cells in *** results demonstrate that this scalable technique can be used to produce groups of lasers with precise emission wavelengths for various nanophotonic and biomedical applications.
