Nonlinear Boost of Optical Angular Momentum Selectivity by Hybrid Nanolaser Circuits
Selective
control of light is essential for optical science and
technology, with numerous applications. However, optical selectivity
in the angular momentum of light has been quite limited, remaining
constant by increasing the incident light power on previous passive
optical devices. Here, we demonstrate a nonlinear boost of optical
selectivity in both the spin and orbital angular momentum of light
through near-field selective excitation of single-mode nanolasers.
Our designed hybrid nanolaser circuits consist of plasmonic metasurfaces
and individually placed perovskite nanowires, enabling subwavelength
focusing of angular-momentum-distinctive plasmonic fields and further
selective excitation of nanolasers in nanowires. The optically selected
nanolaser with a nonlinear increase of light emission greatly enhances
the baseline optical selectivity offered by the metasurface from about
0.4 up to near unity. Our demonstrated hybrid nanophotonic platform
may find important applications in all-optical logic gates and nanowire
networks, ultrafast optical switches, nanophotonic detectors, and
on-chip optical and quantum information processing
