Wen-Chieh Chiang Study on Reducing Measurement Uncertainty: Measurement of Lossy Mode Resonance Based Sensors
Yu-Cheng Lin, Wen-Chieh Chiang, Ya-Ru Tsai, Jia-Wei Hu, Ming Chuan University (Taiwan)

This study takes LMR (Lossy Mode Resonance) spectral measurement as an example, and the measurement uncertainty Type A evaluation method is applied to find a better measurement solution to reduce the measurement uncertainty under the same confidence level. We use the glass coated with ITO (Indium Tin Oxide) film as the LMR sensor to observe the average standard deviation of the LMR resonance wavelength for the measurement system composed of different broadband light sources and different spectrometers. The measurement uncertainty was analyzed, and finally, a suggestion is proposed to reduce measurement uncertainty.

Yi-Hsiang Hsu Highly Sensitive Open-cavity FPI Pressure Sensor Formed by Using Triangularly-ground Fiber
Yi-Hsiang Hsu, Chin-ping Yu, National Sun Yat-sen University (Taiwan)

An open-cavity Fabry-Pérot interferometer (FPI) sensor formed by splicing a hollow-core fiber with a triangularly ground SMF is proposed. Very high gas pressure difference sensing sensitivity of 28.79 pm/psi can be realized. The proposed sensor also shows good repeatability and low temperature response of 0.2 pm/℃.

Thi Anh Nguyet Nguyen Detecting circulating tumor DNA by InGaN quantum wells
Thi Anh Nguyet Nguyen, Fan-Ching Chien, Kun-Yu Lai, National Central University (Taiwan)

Circulating tumor DNA of lung cancer was detected by a surface-enhanced Raman spectroscopy (SERS) biochip built with InGaN quantum wells (QWs). The nitride QWs were grown by metal-organic chemical vapor deposition. It is found that the QWs can enhance the sensitivity and reliability of DNA SERS signals. The result is due to abundant surface charges provided by the QWs.

Hsiao-Yu Hsu High Performance Photo Thin-Film Transistor with Amorphous Indium Tungsten Zinc Oxide
Hsiao-Yu Hsu, Yu-Chuan Chiu, Yu-Han Chen, Po-Tsun Liu, National Yang Ming Chiao Tung University (Taiwan)

Recently, many researches indicate that there are plenty of the advantages of amorphous oxide semiconductors (AOSs), including low-temperature large-area deposition, high electron mobility, and mechanical flexibility. Meanwhile, several excellent review papers represent AOSs are a reliable and practical material. In these papers, IGZO has a lot of attention, but gallium which is rare makes IGZO extremely expensive. Therefore, we use InWZnO instead of IGZO in our experiments and successfully complete to make switches and Resistive Random Access Memory (RRAM). The major of this review is to use InWZnO on optical sensor and get good result.

Anna Milatul Ummah The Highly Potential of Wide Bandgap of MnPS3 and CdPS3 for Optical Sensing
Anna Milatul Ummah, Ching Hwa Ho, National Taiwan University of Science and Technology (Taiwan)

The characterization of MnPS3 and CdPS3 have been worked in this report, including the structural and optical properties. Both materials were grown by CVT method and the monoclinic structure was investigated by XRD spectra and TEM. Band-edge excitons of few-layer MnPS3 and CdPS3 were characterized via micro-thermal-modulated reflectance (μTR) and transmittance measurements from 20 to 300K. As resulted, the ionic bonding of MPX3 family contributes to the large bandgap and high sensitivity behavior, representing the hugely potential application in photodetector, optoelectronics and photo(electro)chemical catalysis.

Quoc Thinh Dinh Investigation of graphene layers on the sensitivity of surface plasmon resonance sensor for Immunoglobulin M Detection
Quoc Hung Phan, Quoc Thinh Dinh, National United University (Taiwan)

This research shows a novel approach using a multiple-layers graphene-based SPR sensor for rapid IgM detection. Measuring the principal fast axis angle of LB (α) of human IgM antibodies in concentrations of 0–250 ng/mL could demonstrate the validity of this sensor. Results show that the resolution of the proposed device is approximately 10 ng/mL and has a result of about three minutes, concluding that selectivity and sensitivity for the detection of IgM antibodies.

silvano donati Laser Diode Self-Mix Interferometer measures vibrations of 0.65 nm rms with just the bias circuit
silvano donati, University of Pavia (Italy); michele norgia, Politecnico di Milano (Italy)

We show that a plain self-mixing interferometer made around a commercial, low-cost laser diode, achieves a sensitivity to small vibrations of 6.5 pm/√Hz, that on a measurement bandwidth of 10 kHz corresponds to a minimum detectable amplitude of 0.65 nm (rms value at SNR=1).

You-Jia Chen Design and Analysis of Dual-Tube Antiresonant Hollow-Core Fiber
Jung-Sheng Chiang, You-Jia Chen, Zong-Wei Lai Lai, Jia-Ming Syu Syu, Nai-Hsiang Sun, I-Shou University (Taiwan)

The guided modes of dual-tube antiresonant hollow-core fibers with different core diameters, thicknesses, and numbers of capillaries for capillary cladding designs by simulation are presented. The proper number of dual-tube capillaries enhances the fundamental mode power, and the 8-capillary cladding of antiresonant hollow-core fiber has the red-shifted as a function of the core diameter.

Yi-Lun Yen Photo Current Generation of the Al/SiO2/Si MIS Device and its Photo-responsivity
Ming Chang Shih Shih, Yi-Lun Yen, I Chieh Wu, Yen Ju Wu, National University of Kaohsiung (Taiwan)

Here we demonstrated the fabrication of an Al/SiO2/Si MIS device and its characterization of photo current generation. Responsivity as high as 1.4 A/W can be achieved at UV (200 nm~300 nm) and IR (800 nm ~ 900 nm) and with high contrast against visible light. In addition, the photo current decreases linearly as the increasing of the thickness of the SiO2 insulating layer. A current drifting mechanism is suggested to explain the result of the photo current characteristics.
