Tzu-Yu Chen Award Candidate Ultrafast Second-Harmonic Generations in a Plasmonic Two-Wire Transmission-Line
Tzu-Yu Chen;Fan-Cheng Lin;Jer-Shing Huang;Chen-Bin Huang

A symmetric plasmonic two-wire transmission-line (TWTL) is successfully used for ultrafast second-harmonic generation (SHG). To our best knowledge, we provide the experimental evidence over SHG using surface plasmon polaritons. Interestingly, regardless of the two potential modes excited at the fundamental frequency, the resulting SHGs are always the asymmetric mode.

Shang-Yang Yu Award Candidate Light-Driven Self-Assembly and Coalescence of Gold Nanorods
Shang-Yang Yu;Yun-Ju Chen;Jiunn-Woei Liaw

Using the irradiation of a linearly-polarized laser, the light-driven oriented attachment and self-assembly of gold nanorods were induced. Process was conducted in a droplet of gold NR colloid on a glass irradiated by LP near-infrared low-power laser beam at room temperature and atmospheric pressure, without any assistance of chemical surfactant.

Yu-Heng Hong Award Candidate Solvent Engineering for Room-temperature Lasing of Lead Bromide Perovskite Thin Films
Yu-Heng Hong;Kao Tsung Sheng

Recently, hybrid metal-halide perovskites have attracted much attention due to their significant optoelectronic properties. However, it is still difficult for room-temperature laser applications of perovskite thin films. In this work, we have used the solvent-engineering process to prepared and demonstrated the room-temperature lasing of lead bromide perovskite thin films.

Bo-zhi Huang Gaussian beam propagation through an anomalous material by phase compensation
Bo-zhi Huang

A beam diffracts in free space due to the phase delay among its angular components. Such spreading beam can be suppressed by the anomalous material and even focused in the anomalous material and in free space. Two anomalous materials with different dispersions were analyzed to show the focusing performance.

Cheng-Ting Liao Enhanced Spontaneous Emission of 2D Transition Metal Dichalcogenide through Large-area Optical Slot Antenna Arrays
Cheng-Ting Liao;Meng-Chieh Yang;Ming-Chang Lee;Yi-Hsian Lee

We study the spontaneous emission rate of 2D transition metal dichalcogenide (TMD) which is enhanced with the aid of a large optical slot antenna array fabricated through a wafer-scale process. A nearly 10-fold enhancement of photoluminescence was experimentally observed

Integrated optical pure phase modulators based on PZT thin films
Jeroen Beeckman

We report on fast electro-optic modulation using hybrid integration of ferroelectric thin films on the SiN photonic platform. Efficient and high-speed modulation is made possible thanks to the high-quality deposition of a thin film of lead zirconate titanate onto the SiN photonic chip.
