High Quality Ta2O5 Nonlinear Waveguide Development And Single Polarization Supercontinuum Generation
Chieh Huang

Through the dispersion engineering and the understanding of the correlation between the various structural parameters of the waveguide and the dispersion, we changed the waveguide structure and matched the SCG mechanism to achieve a single polarized SCG and verified it through the measurement system.

Tantalum pentoxide nonlinear waveguide and its application for ultra-broadband light source
Kao Feng Jung

We design the channel waveguide by calculating the dispersion engineering, and use E-gun to deposit the Ta2O5 film as the waveguide core, and use light pulse to drive into the optical waveguide to generate SCG. Finally, we explore the transmission behavior of light in the waveguide by using the NLSE.

10/20 GHz optical frequency stable mode-locked fiber laser with cavity length feedback control
Mei-Chun Chen;Hsiang-Yu Wang;Yinchieh Lai

A 10/20 GHz optical frequency stable mode-locked Er-fiber laser is demonstrated by adding an intra-cavity high Finesse Fabry-Pérot etalon (FSR=10GHz) and employing the cavity length feedback control. Stable laser operation can be maintained within the compensation range of the cavity length feedback control system.

Reveal the Mechanism of Current-Voltage Hysteresis in Perovskite Solar Cells using the Poisson and Drift-Di usion Model with Ion Migration Model
Jun-Yu Huang;En-Wen Chang;Yuh-Renn Wu

In this work, a modified Poisson and drift-diffusion solver coupled with a fully time-dependent ion migration model is developed and applied to demonstrate current–voltage hysteresis behavior and analyze how ion migration affects the performance and hysteresis of perovskite solar cells. The modeling results reveal the physical mechanism of hysteresis induced by ion migration. The most crucial factor in the hysteresis behavior is the built-in electric field of the perovskite. Using the developed solver, the non-linear hysteresis curves are demonstrated under different scan rates, and the mechanism of the hysteresis behavior is explained. The findings reveal why the change in hysteresis degree with scan rate is Gaussian shaped rather than monotonic. Additionally, some factors affecting the degree of hysteresis are modeled. The main factors contributing to the degree of hysteresis are determined to be the degree of degradation in the perovskite material, the quality of the perovskite crystal, and the materials that make up the electron transport layer (ETL), which correspond to the total ion density, carrier lifetime of perovskite, and the properties of the ETL, respectively.

Multiple vector soliton from passive mode-locked Erdoped fiber laser based on graphene oxide
Zhan-Yao Zhang;Zhen-Ying Li;Shwu-Yun Tsay;Yao-Hui Chen;Ja-Hon Lin

Through polarization beam splitter outside cavity, the multiple vector solitons hvave been demonstrated from a mode-locked erbium-doped fiber laser (EDFL) based on the GO/PVA film. Here, the fundtamental mode-locked (FML) soliton was observed in horionztal axis bu the coexiting of FML and multiple soliton was observed in vertical axis.

Characteristics Analysis of Perovskite-Based Surface Plasmon Nanolasers
Qi-Yan Zheng;Pi-Ju Cheng;Tien-Chang Lu;Mao-Kuen Kuo;Tzy-Rong Lin

We systematically studied the characteristics of hybrid perovskite-based surface plasmon nanolasers. If one changes the anion composition of perovskites, the emission wavelength can be easily tuned. We conducted in full-spectrum modeling that featured perovskite nanowires placed on different SiO2-coated metallic (Ag, Al, and Au) plates and exhibited low-transparency threshold-gain.

Contact Resistance between TMDs and Metals: A First Principles Study
Hamideh Vaezi Kakhki;Long Hsu;Yin-Guo Wang;Ken-Ming Lin

T phase of monolayer MoSe2 as a buffer connected with scandium leads and monolayer MoSe2-H was evaluated. The Density Functional Theory (DFT), Non-Equilibrium Green’s Functions (NEGF) and Landauer formula were used to calculate the current density between two leads. Our strategy can satisfy the industry’s criterial.

A Method Of Depressing Mikania Micrantha Growth By Blue Laser Irradiation On Stems
Wei-Yung Weng;Yu-Pin Lan

Here observes the mortality of Mikania Micrantha after irradiating different energy of the laser and variation of the laser beam covering the stem dimension of Mikania Micrantha. This method effectively depresses the Mikania Micrantha growth by exposing stems on a blue laser diode at a wavelength of 455nm.

Chieh Lo;Shih-Kun Lin;Chao-Hsin Wu

This paper focuses on the design and fabrication of high power single-mode distributed feedback (DFB) lasers. We tuned the grating pitch to analyze and optimize a single-mode 1310nm DFB laser. Ridge waveguide DFB lasers with the optical power of 100mW and SMSR 45dB was fabricated.

Shi-Yu Hsiao;Zong-Han He;Che-Chung Chou;Tyson Lin

We design a experiment on an optical breadboard by using the Bode analyzer of Red Pitaya STEMlab to measure the light speed. A low-cost laser module is modulated. The modulated light beam is detected at two locations separated by 0.975 m. The error of the measured light speed is 2.01%.
