| Summary: | The ability to manipulate microlaser performance is highly desirable so as to promote on-chip classical and quantum information-processing technology. Here, we demonstrate that mode manipulation of bottle microresonators is enabled by precise deposition of single gold nanoparticles in a reconfigurable and selective manner. Numerical investigation reveals the mechanism of introducing optical loss via single Au NP scattering. Experimental results show that the lasing action of cavity modes could be efficiently suppressed, and single mode lasing is successfully achieved with a high side mode suppression factor ∼13 dB. |
