We present high performance silicon photonic circuits (PICs) defined for off-chip or on-chip photonic interconnects, where PN depletion Mach-Zehnder modulators and evanescent-coupled waveguide Ge-on-Si photodetectors were monolithically integrated on an SOI wafer with CMOS-compatible process. The fabricated silicon PIC(off-chip) for off-chip optical(More)
The purpose of this study is to verify the structural relationship among affective characteristics, cognitive characteristics, students' participation, and course-retaking intention in e-learning environment. Web survey was conducted from one university in Korea and 210 students participated in this survey who already took e-learning courses. A hypothetical(More)
This study seeks to investigate research trends on e-learning in Korea for the past 10 years and meta-analyze relations between e-learning and its effectiveness with an eye on confirming the effectiveness of e-learning. The analysis showed that there is a high correlation between changes in the society's overall interest in e-learning and the number of(More)
