Wei Kang Liu SOI micro-ring modulator with RZ-OOK signal
Wei Kang Liu,Chun Yen Chen,Chia Chien Wei,Yung Jui Chen,

We propose a numerical method to evaluate the dynamic response of SOI micro-ring modulator. The overshoot effect in ring has controlled by RZ format signal and the photon lifetime is verified to enhance the signal. Thus, the performance of the signal can be improved in high speed modulation applications.

Lin Yen-Ju Analyzing the Sensitivity of Silicon and Germanium Avalanche Photodetectors with the Inclusion of Dead Space Model and Dark Current Model
Lin Yen-Ju,Chen Ku-Hung,Liu Han-Din,Kang Yimin,LeeM Ming-Chang,Na Neil,

This is a numerical model for calculating three parameters of device performance. The relationship of dead space and two sources of noise, the effective ionization coefficient ratio and dark current on the device performance is established. In addition to investigating different parameters, a device sensitivity analysis is provided and the trade-off between parameters is discussed.

Wei-Fan Lin MHA and DL-cysteine Modified AuNPs on n-type Ge Photodetectors
Wei-Fan Lin,Hao-Tse Hsiao,I-Chih Ni,Shien-Der Tzeng,Chu-Hsuan Lin,

Gold nanoparticles modified by different molecules, including 6-mercaptohexanoic acid (MHA) and DL-cysteine, are deposited on n-type germanium photodetectors to enhance the responsivity. Different modification molecules may have different influence on the responsivity. The DL-cysteine results in a responsivity of 4000 mA/W at the wavelength of 1310 nm, and the corresponding efficiency is even much larger than 100 %.

WJ Fan Bowing effect of L-valley bandgap on optical gain of Ge/GeSiSn quantum well
WJ Fan,

The multipule-band k.p method is applied to calculate the optical gain of n+ doped strained Ge/GeSiSn quantum well (QW) including the L-valley’s influence and many-body effect. The bowing effect of L-valley bandgap plays a very important role on the optical gain including many-body effect.

Chun Wang Photonic Crystal Hybrid Microdisk
Chun Wang,Tsan-Wen Lu,Po-Tsung Lee,

High Q transverse-magnetic polarized photonic crystal microdisk is investigated. Directional emissions can be obtained via inducing a nanocavity to break its rotational symmetry. Further laying this microdisk on silver substrate with horizontal air slot, high Q/V (~ 2×10^5λ^-3) plasmonic-photonic hybrid mode is obtained under very small device footprint of 9μm^2.

ChunChi Lin Design of an Organic-Silicon Photonic Crystal Nanoslot Cavity LED/Laser
ChunChi Lin,Neil Na,

We design a photonic crystal nanoslot cavity LED/laser immersed in a fluid containing near-infrared optical dyes by finite difference time method. By modulating the nanoslot cavity at in-phase electric field antinodes, we can control the mode volume, quality factor and far-field emission pattern to reach a vertical emission. The nanoslot cavity have Q = 1283, V =0.059 (λ/2n_fluid)^3 with vertical emission at 1.31 μm, which may be applicable to the next-generation light source for high-speed optical interconnects.
