Optical Devices for Pre-Collimating and Guiding Edge-Emitting Laser Diodes via Multiphoton Microfabrication
Yan-Shuo Chen;Shuo-Je Hsieh;Chia-Yuan Chang;Shean-Jen Chen;Chien-Chung Lin;Chun-Hong Chen
Multiphoton excitation (MPE) technique is utilized to create three dimensional (3D) structures via polymerization in trimethylolpropane triacrylate (TMPTA) solution. Due to the structures that microfabrication is based on Vector Scan, the microfabrication time is fastest than Raster Scan. We can be more efficient at microfabrication.

Monitoring the resonant wavelength shift based on a gradient guided-mode resonance filter
Chih-Wei Chang;Shi-Ting Chen;Yi-Ming Lin;Cheng-Sheng Huang
A resonant wavelength detection system based on a gradient grating period guided-mode resonance filter and a linear charge-coupled device is demonstrated. We successfully demonstrate that by using this system, we can correlate an optical sensor’s dip wavelength to the peak at intensity measured at a CCD

Microlens Array on CCD Chip as Wavefront Sensors via Two-Photon Polymerization
Zhi-Jia Liu;Jian-Heng Chen;Yi-Pin Chen;Shean-Jen Chen
Conventional Shack-Hartmann wavefront sensor (SHWS) consists of separated microlens array (MLA) and CCD. In this study, we build an extremely miniature SHWS via fabricating the MLA directly on CCD chip with two-photon polymerization (TPP) system. By utilizing Fresnel zone plate design, 54% of the fabrication time can be further reduced.

Optical and Color Quality Simulation of Flexible White Organic Light Emitting Diodes
An-Chi Wei;Jyh-Rou Sze;Wei-Xuan Ho
The purpose of this research is to establish an optical model for the flexible white OLEDs. We build the optical models with different bent radii and then compare these models. We will study the color temperature and color rendering index as well as the optical properties of these devices.

Rapid Shack-Hartmann Wavefront Sensor for Adaptive Optics System via FPGA-embedded Camera Link
Jih-Liang Hsieh;Yi-Pin Chen;Yu-Chen Chang;Chia-Yuan Chang;Shean-Jen Chen
Field programmable gate array (FPGA) is suitable for real-time parallel image processing and Camera Link can provide extremely high data transmission bandwidth. By combining an FPGA-embedded Camera Link frame grabber, a Shack-Hartmann wavefront sensor is built to perform rapid wavefront measurement at 266 Hz for adaptive optics system.

Design and Simulation of Micro Lenses for Silicon-based Photodetectors
Chung-Chih Lin;Allen Chu;Neil Na;Likarn Wang
We design two types of micro lenses to increase the effective active area of silicon-based photodetectors. The first one is a Fresnel zone plate lens, which can be fabricated by standard CMOS process technique. The second one is a hemisphere lens, which can be fabricated by binary phase grating technique.
