[ 1 ] - طراحی و ساخت میکروآیینه شکل‌پذیر پلیمری جهت استفاده در سیستم‌های اپتیک تطبیقی

This paper presents a novel method for the fabrication of polymeric deformable micromirror based on electrostatic actuator. Deformable micromirros are commonly used to correct optical wavefront aberrations in the adaptive optic systems, and thus, they need a deformable diaphragm. In this study, the diaphragm of micromirror is made from SU-8 polymer which is mounted on the fixed electrode arrays...

[ 2 ] - آنالیز تاثیر نقص در لبه موجبر تپه‌ای ساخته شده در لیتیوم نایوبایت

In this research, the capability of new approach of making ridge waveguides in lithium niobate by Argon physical etching and diffusion of titanium is investigated. For this purpose, the proportion of light mode confinement in the ridge section is measured and compared to simulation results. Also the effect of ridge wall defects -which is a challenge of this kind of waveguides- in light power di...
