Abstract

Both the current long term telecommunication trends toward optical networking and the recent growth in information bandwidth have pushed the necessity for improved optical communications. Our fabrication approach, which leverages our expertise in solid freeform fabrication in conjunction with sol‐gel technology, has advantages over these other methods because of the inherent benefits of using a direct‐write philosophy, such as design flexibility and minimal post‐processing. However, fabrication of such novel optical components requires extensive knowledge of their light guidance capabilities. This paper shows the technical issues involved in both modeling and characterizing small optical components fabricated by locally densifying sol‐gels in a modified direct‐write process.

Abstract

Although the civil rights movement in the United States occurred more than 50 years ago, voter suppression, as witnessed in the 2012 election, for diverse groups of people continues. The information presented in this article supports the teaching and learning of social studies within early childhood and elementary grades as teachers and students consider and examine issues and problems concerning those who have been disenfranchised as voters within the United States. The use of historic role models, artwork, musical lyrics, and primary documents are various ways to assist young learners as they analyze and confront controversial issues such as discrimination within a pluralistic society. Through research, young learners can construct narratives from the present to make meaning from historical figures, events, and places of the past. Children’s understandings of historical people and events that took action against discriminatory practices and opportunities to expand learning about the topic may enable them to take the lead to make our democracy a reality for life, liberty and happiness.
