Dispersion-engineered TiO2 metasurfaces
Wei Ting Chen
Optical dispersion results from the index of refraction of a material varying with the frequency of incident light. Accurate control over this property is vital. For example, it mitigates pulse spreading in optical fibers, which are the backbone of modern telecommunications, and enables pulse compression in ultrafast laser optics (2018 Nobel Prize in Physics). In this talk, I will begin with an introduction to the design, simulation, and fabrication of metasurface components with a focus on metalenses. Subsequently, I will illustrate how to control metasurface dispersion by customizing the group delay and group delay dispersion of constituent nanostructures. Such dispersion-engineered metasurfaces enable achromatic metalenses, aberration-corrected spectrometers, as well as lens-aberration correctors designed for simple singlets to complicated microscope objectives. My talk will be summarized by detailing on-going works involving metasurface-enabled superachromatic and broadband high-efficiency lenses and pointing out future emerging applications. These demonstrations are vastly applicable to machine vision, autonomous vehicles, optical communication, augmented and virtual reality devices, and more.

Owing to the shortcomings of graphitic carbon nitride, nanostructured tin (II) sulfide was sculptured via physical vapor deposition to overcome the inherent limitations of graphitic carbon nitride, such as fast charge recombination rate and narrow absorption spectrum. Here we fabricated SnS/g-C3N4 nanostructured films for photoconversion of CO2 into solar fuels.

Li Guan Li;Wang Yao Te
This experiment investigates the influence of annealing under NH3 ambient on the electrical properties of Ag-doped ZnO thin films. According to the hall measurements, Ag- doped ZnO thin films obtained higher carrier concentration after NH3 annealing. It maintained the p-type behavior and the hole concentration increased to 1.087x1017cm-3 from 2.696x1016cm-3.

Simulation-Based Omnidirectional Blue Light Bragg Reflector Design by Multi-Central Wavelength Method Using Nb2O5/SiO2 Stacks
Chiu-Man Jiang;Yen-Chi Huang;Cheng-Yen Chen;Cheng-Jia Gong;Chung-Chieh Liao;Ching-Hsuan Shih;Jing-Jenn Lin
The reflectivity of Bragg reflector actually changes with the incident angle of light. In this work, measured optical parameters of Nb2O5 and SiO2 deposited by e-beam evaporation were used to simulate for the optimal design parameters of omnidirectional blue light Bragg reflector. The simulator was written in MATLAB programming language.

A Simulation Study on Electron-Beam Evaporated Nb2O5/MgF2 Bilayers for Omnidirectional Reflection of Blue-Light Bragg Reflector Applications
Po-Hung Yu;Hong-Zhe Jhou;Yun-Hen Wu;Yu-Yun Wu;Jing-Jenn Lin
This paper simulates the optimal parameters for an omnidirectional blue-light Bragg reflector design by adjusting the thickness ratio of materials of Nb2O5 and MgF2 at a fixed thickness of 1/4 wavelength for a single bilayer. Simulation results showed that the blue light at various incident angles maintained reflectance above 95%.
