Selective control of light is essential for optical science and technologywith numerous applications. Nanophotonic waveguides and integrated couplershave been developed to achieve selective coupling and spatial control of anoptical beam according to its multiple degrees of freedom. However, previouscoupling devices remain passive with an inherently linear response to the powerof incident light limiting their maximal optical selectivity. Here, wedemonstrate nonlinear optical selectivity through selective excitation ofindividual single-mode nanolasers based on the spin and orbital angularmomentum of light. Our designed nanolaser circuits consist of plasmonicmetasurfaces and individual perovskite nanowires, enabling subwavelengthfocusing of angular-momentum-distinctive plasmonic fields and further selectiveexcitation of single transverse laser modes in nanowires. The opticallyselected nanolaser with nonlinear increase of light emission greatly enhancesthe baseline optical selectivity offered by the metasurface from about 0.4 upto near unity. Our demonstrated nonlinear optical selectivity may findimportant applications in all-optical logic gates and nanowire networks,ultrafast optical switches, nanophotonic detectors, and on-chip optical andquantum information processing.
