Nanophotonics
Our goal is to understand and manipulate optical processes on the nanoscale.
|
|
Micro lasers - We design, fabricate and study various microcavity shapes to tailor lasing properties.
Nano lasers - We have developed a subwavelength all-dielectric laser which can be fabricated by standard photolithography and wet etching.
Nanoplasmonics - Near-field scanning optical microscopy allows us to probe the transport and
localization of surface plasmon polaritons in metal-dielectric nanostructures.

Complex Optical Materials & Phenomena
We utilize complex structures, from random, quasi-ordered, to aperiodic and periodic, to control light transport, localization, absorption, emission,
amplification and lasing.

|
Random lasers - We have invented a new type of microlaser - a micro random laser - by utilizing strong scattering for optical confinement.
UV Photonic Crystal Light Sources - We employ photonic band gaps and slow light to improve the performance of UV lasers and LEDs.
Mesoscopic transport of photons - We investigate the effects of coherent amplification and optical nonlinearity on mesoscopic transport of photons in random and aperiodic structures.

Biophotonics
We aim to harness the best of nature's photonic structures and utilize advances in materials technology to achieve novel and advanced
functionality.

Structural color - We investigate the physical mechanism for color production by isotropic nanostructures with short-range order in bird feather barbs.
Biomimetics - We fabricate isotropic nanostructures with short-range order which produce non-iridescent colors over a wide viewing angle.
