The specific challenges being addressed in this thesis are: 1) high fiber-to-chip coupling loss, 2) lack of high density fiber-to-chip coupling solutions, and 3) high cost active fiber alignment. The optimized optical interconnection is able to achieve \u0026lt; 2 dB of coupling loss at fiber-like alignment tolerance. It includes a parallel-processed 45\u00b0 turning mirror, and a fiber alignment groove in glass to allow passive alignment. The results demonstrated in this research confirm the cost, performance, and density advantages of glass interposer technology for short-distance optical communications.\u003C\/span\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Low Loss and High Tolerance Out-of-plane Single-mode Optical Interconnections in Glass Interposers "}],"uid":"28475","created_gmt":"2016-09-27 18:05:36","changed_gmt":"2016-09-27 20:07:31","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-09-30T13:30:00-04:00","event_time_end":"2016-09-30T15:30:00-04:00","event_time_end_last":"2016-09-30T15:30:00-04:00","gmt_time_start":"2016-09-30 17:30:00","gmt_time_end":"2016-09-30 19:30:00","gmt_time_end_last":"2016-09-30 19:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"121341","name":"graduate students. defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EECE Graduate Office\u0026nbsp;\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
