Strong Luminescence Enhancement of WSe2 Monolayer by Metal/Insulation/Metal Metasurface
Chun-Wen Chen;Yu-Wei Liu;Muhammad Adil;Hsiang-Ting Lin;Andrew Boyi Lee;Hai-Pang Chiang;Tsung-Sheng Kao;Min-Hsiung Shih

In the work, we had integrated the tungsten diselenide (WSe2) atomic layer with the metal/insulation/metal (MIM) metasurface. The local surface plasmon resonance (LSPR) in MIM structure was optimized to match to the optical emission of the WSe2 monolayer. A 27-time enhancement in WSe2 optical luminescence was achieved in the experiment.

Continuously-chirped guided mode resonance filter for low-cost near-infrared spectroscopic applications
Lin Chih-Yueh

We demonstrate a Si-based period-chirped guided mode resonance filter to discriminate telecom o-band wavelengths with a filter linewidth of 1.04 nm, thus enables on-chip spectroscopy for near-infrared light with low cost.

Ge Waveguide Light-Emitting Diodes at 1550 nm on Germanium-on-Insulator Platform
Po-Lun Yeh;Cheng-Sung Tsai;Guo-En Chang

We report on Ge waveguide light-emitting diodes on a germanium-on-insulator (GOI) platform. Room-temperature electroluminescence at 1550 nm was demonstrated and the optical properties of the devices are investigated. These results present an important step toward electrically-injected light sources for GOI-based electronic-photonic integrated circuits.

Extremely High Aspect-ratio Sliver Nano-structure by Nanosphere Lens Lithography
Chia-Ling Tsao;Chieh-Chun Chang;Szu-Yung Huang;Yung-Chong Chang

A new high aspect ratio nanostructure fabricated by nanosphere-lens-lithography (NSL) to create an array of two silver-heaps by metal evaporation. By utilizing the COMSOL simulation, we optimize the scattering performance from 760-1460nm. Combining with surface-plasmon-resonance(SPR), we could gain a promising application on optical trapping, with low cost and commercial fabrication.

Silicon Micro-hole Array for Silicon-Germanium Infrared Photodetector
Yi-Hsuan Huang;Yu-Cheng Tsai;Zingway Pei

Ge-filled Si micro-holes were suggested and demonstrated for high-efficiency 1550 nm photo-absorption in this work. By this structure, a high-density infrared (1550 nm) photo-receiver integrated optoelectronics could possibly be implemented on Si. With a 6μm depth micro-hole array, the 1550nm infrared light absorbance is 4.6 % higher than silicon-based structure.

A Metal Embedded Package Structure for Hybrid Colloidal Quantum Dot LEDs
Yang Jhen jia

To realize the light and thermal impact on the quantum dots, the CdSe/ZnS quantum dot in toluene solution was mixed with polydimethylsiloxane and then filled on the LED. We designed two package structure to encapsulate four different luminance intensity blue light emitted diode in 5070 lead frames respectively.

Development of novel SERS substrate to detect molecules at extremely low concentrations
Rahul Ram Panjalimgam;Sajal Biring;Chih-Yi Liu

Detection of molecules at extremely lower concentrations is demonstrated successfully on a surface-enhanced Raman spectroscopic (SERS) substrate fabricated by electrochemical deposition of silver nano-particles into thin walled nano-channels of anodic aluminum oxide (AAO). The silver nanoparticles deposited into the nanochannels facilitates the detection of molecules at lower concentrations.

High Efficiency SERS Detection by the ZnO Multipods Decorated with Silver Nanoparticles
Elumalai Ashok Kumar;Yu-Hsu Chang;Tzyy-Jiann Wang

Effective enhancement of SERS signal by the action of strengthened electromagnetic field and the electron accumulation at the semiconductor/noble-metal junction using ZnO/Ag hybrids is presented. The obtained limit of detection is as low as 10^-14 M and the enhancement factor is about 10^11.
