Novel dye random lasers from silk fibroin film with embedding of silver nano-particles
Po-Han Tung;Bing-Yi Hung;Tzu-Chau Lin;Ja-Hon Lin

We investigated plasmon random laser from dye-covered silk fibroin (SF) without or with the embedding of silver nano-particles (AgNPs). Owing to the localized surface plasmon resonance, the random lasing efficiency have been greatly enhanced through the localized surface plasmon resonance and the increase of recurrent light scattering from the AgNPs.

Coherence studies of random lasers by Michelson interferometer
Jian-Xuan Liu;Tsung Sheng Kao

We use Michelson interferometer to measure the coherence of random laser, By characterizing the coherence of random laser gives us a chance to understand the optical feedback due to multiple scattering mechanism. We present our experimental setup and result to quantify the coherence of random laser system.

Fabrication Study of Semiconductor-based 625nm Red Micro LEDs
Yi-Young Lee

In this paper, we demonstrated the light-emitting diodes (LEDs) are self-emissive and can be miniaturized to meet these requirements. The main research is focused on reducing the area of the light-emitting diode to improve the resolution of the display.

CMOS-Compatible Plasmonic Terahertz Emitter

We demonstrated a complementary metal-oxide semiconductor (CMOS) compatible plasmonic terahertz photoconductive antenna using GeSn as the photoconductive material. This novel terahertz (THz) emitter pumped with 1550 nm femtosecond (fs) laser provides bandwidth up to 1 THz and signal-to-noise ratio (SNR) 40 dB.

Wide-field quantitative biomedical imaging based on multi-tap CMOS image sensors
Keiichiro Kagawa

Multi-tap CMOS image sensors, where a pixel is composed of a single photodiode and multiple storage diodes, can implement functional imaging with the programmable exposure capability. In this talk, example applications of these image sensors to wide-field quantitative tissue imaging such as spatial frequency domain imaging, multi-exposure laser speckle contrast based blood flow imaging, and so on.
