Shao-Wei Wang Award Candidate A Bi-parameter Sensor Based on A Fiber Fabry-Pérot Interferometer Combined with A Fiber Bragg Grating
Shao-Wei Wang;Hsiang-Ting Peng;Hung-Ying Chang;Wen-Fung Liu;Chin-Ping Yu

A bi-parameter fiber sensor formed by sandwiching a 50-m HCF between a SMF and a FBG is proposed. The temperature and strain sensitivities of the HCF-based FPI dip and FBG peak can be successfully obtained. We have also constructed the sensitivity matrix for simultaneously sensing the temperature and strain.

H.C Wu Award Candidate Athermal Ta2O5 Waveguide Filters and Resonators for Si Photonics
H.C Wu;Y. Y. Lu;A.K. Chu

Athermal Ta2O5 waveguide devices, including waveguide filters and resonators, were proposed for Si photonics. The filter temperature-dependent Bragg wavelength shifts of TE mode with the SOG and oxide claddings are -16.9pm/K and 7.4pm/K. Moreover, resonators with oxide cladding shift 8.2pm/K, which are 10 times better than conventional silicon waveguide devices.

Chia-Jui Chang;Tien Chang Lu;Yu-Shun Chou

Surface plasmon polariton nanolasers operating at near surface plasmonic frequency shows ultrahigh relaxation frequency over terahertz range due to the strong light matter interaction to boost the Purcell effect and spontaneous emission coupling factor.

Shi-Yuan Lin;Chin-Ping Yu

We present a refractive index sensor based on an open-cavity fiber Fabry-Pérot interferometer. The open cavity is fabricated by splicing a HCF between a polished SMF and a commercial SMF. A high refractive index sensing sensitivity of 1162.94 nm/RIU can be obtained.

Chia-Wei Huang;Ya-Ching Liang;Jyun-Fu Shih;Tzu-Hsiang Yen;Jia-Jin Lin;Chun-Hu Chen;Yung-Jr Hung

We realize a low-loss (~5 dB/cm), high-extinction-ratio (> 27 dB), and narrowband (0.335 nm) GO/silicon hybrid waveguide Bragg reflectors by transferring thin GO gratings atop silicon strip waveguides. This device exhibits stable reflecting wavelength and controllable reflection bandwidth that can be well predicted by numerical simulations.

Yuan-Chia Chang Award Candidate Utilizing Silicon-Photonic Micro-Ring-Resonator and Multiple-Ring Cavity for Stable and Switchable Erbium Fiber Laser with Single-Longitudinal-Mode
Yuan-Chia Chang;Yung Hsu;Chien-Hung Yeh;Chi-Wai Chow;Hao-Yun Cheng

We proposed a stable and wavelength-switchable erbium-doped-fiber (EDF) laser by utilizing the silicon-micro-ring-resonator (SMRR) and multiple-ring scheme. The wavelength can be tuned from 1544.35 to 1564.10 nm with a ~2.0 nm tuning step and reach the single-longitudinal-mode (SLM) output of 35 kHz linewidth, and optical-single-to-noise-ratios (OSNRs) of >54.9 dB.

Chen-Ming Chung Award Candidate Displacement Sensor Based on Whispering Gallery Mode on a U-shaped Photonic Crystal Fiber
Chen-Ming Chung;Chin-Ping Yu

We propose a highly sensitive displacement sensor by using two translation stages to bend a PCF into U-shape. As the bending diameter decreased to 4.3mm, the WGM is induced, and a clear interference dip can be observed. By applying variant displacement, the measured displacement sensitivity is 179 pm/μm.

Yung-Ju Huang Award Candidate The study of characteristics of the metal-insulator-metal defect nano-ring plasmonic waveguide structure
Yung-Ju Huang;Yaw-Dong Wu

In this paper, we study the characteristics of the Metal-Insulator-Metal (MIM) plasmonic defect nano-ring waveguide structure. The numerical results show that the resonant waveguide of the defect naon-ring has a linear relationship. The finite-difference time-domain method (FDTD) is employed in the simulations. This investigatory may assist researchers design in nano-photonic-IC.
