What is it about?

We report the optical trapping and manipulation of cylindrical zinc oxide nanowires using an all-dielectric silicon nanononamer at 1064 nm wavelength for designing wavelength-tunable on-chip nanolasers. This integrated framework synergistically embeds two functionalities: optical tweezers for trapping and assembly with silicon nanononamers; energy source, gain medium and optical cavity for lasing with multiple hotspots and with zinc oxide nanowires.

Why is it important?

The integration of laser sources on a chip has always been considered a key milestone in the evolution of optical computing platforms. For this work, the simple nanowire-based silicon photonic platform is compatible with the complementary metal–oxide–semiconductor technology, which allows low-cost fabrication of such structures and the integration with other on-chip optical components.
