Wan-Ting Chien Award Candidate BSA-assisted fabrication of graphene oxide quantum dot-based microstructures


Three-dimensional (3D) graphene oxide (GO)-based microdevices are potential to be useful for biomedical applications, which can be fabricated by two-photon excitation. In this study, 3D-freeform GO quantum dots (GOQD)-based microstructures at different GOQD concentrations were developed by two-photon crosslinking (TPC) femtosecond laser direct writing and arbitrary adjust the GQD concentration.

Yuan-Ting Lo Award Candidate Ultrathin Planar Optical Lensing Functions via Quasi-periodic Nanohole Arrays


In this paper, the lensing functions and imaging abilities have been theoretically investigated and demonstrated. Such an optical binary mask designed in a quasi-periodic arrangement can function as an ultrathin planar optical lens. By different application, its produce an alternative method to achieve the imaging functions as a conventional lens.

Bo-Song Huang Award Candidate Ultrathin InGaN Light Emitting Membranes


300nm-thick InGaN light emitting membranes (InGaN-LEM) has been demonstrated through a chemical separation process. The lateral wet etching rate on the sacrificial layer was measured at 250μm/min for the separation process. Strain-induced piezoelectric field of the InGaN membrane was analyzed through photoluminescence spectra. At 0.5mA operation current, the electroluminescence peak wavelength of InGaN-LEM (458.4nm) has a 3.8nm redshifted compared with ST-LED (454.7nm).

Jeng Yi Lee Award Candidate Phase diagram to design passive scatterers


Owing to power conservation law, we propose a universal phase diagram for complex scattering coefficient, showing its power competition among scattered and absorbed power and scattered field limitation, regardless of geometrical construction and of any constitutive parameters. With electrically small core-shell scatterers as an example, a systematic method to design field-controllable scatterers is demonstrated in the phase diagram.

Kuan-Yu Li Saturable Scattering in Gold Nanostructures


Nonlinear scattering in the gold nanoantenna is studied with peak wavelength of surface plasmon resonance. Surprisingly, the threshold is similar to gold nanospheres, manifesting that extraordinary field enhancement of the antenna is not the dominating mechanism.

Meng-Ying Lin Optical Tamm States in Cholesteric Liquid Crystal with Metasurfaces


ABSTRACT—Optical tamm state couldn’t be directly excited by external field between cholesteric liquid crystal (CLC) and metal, because of the phase change. However, by using metasurfaces and CLC, optical tamm state could be excited at the boundary. The position of resonance dip could be controlled by varying thickness of the spacer or changing the center wave-length of CLC.
