Low-dimensional optical nanomaterials
Low-dimensional nanomaterials with excellent electrical and optical properties hold great promise as key building blocks for nanoelectronics, photonics, optoelectronics and bio/chemical applications. We are interested in understanding and describing the fundamental optical properties of nanomaterials that can enable us to engineer their optical response and explore their potential as novel photonic components and devices.

Light scattering of nanowires
Nanostructured silicon nanowires and size-dependent resonant light scattering. Left: SEM images of diameter-modulated silicon nanowires. Right: dark-field optical microscope images of the nanowires showing unique coloration stemming from spatially localized resonant light scattering.

Deterministic assembly of a nanowire and active waveguiding
Predesigned nanopatterns in a resist layer enable deterministic assembly of nanowires with precisely controlled position, geometry, and alignment.
In photoluminescence experiment, excited CdS nanowire emits light that partly couples to nanowire waveguide modes and propagate through the nanowire.
