The work addresses a key limitation in current atomic clock and quantum sensor technologies, namely the reliance on manual assembly and bulk optical components, which constrain scalability, increase cost, and limit manufacturing yield. The proposed approach introduces a wafer-level fabricated, piezoelectrically actuated micromirror capable of achieving a precisely controlled 45\u00b0 tilt with high optical reflectivity. This micromirror is integrated with a microfabricated silicon collimator to realize a planar atomic beam architecture. By eliminating the need for buffer gas, the system enables nearly transit-time-limited linewidths, improving long-term stability while mitigating drift mechanisms associated with buffer gas interactions.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"A Hybrid Atomic MEMS Platform for Miniature Atomic Beam Devices and Applications"}],"uid":"28475","created_gmt":"2026-04-14 12:06:16","changed_gmt":"2026-04-14 12:06:31","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-04-21T10:00:00-04:00","event_time_end":"2026-04-21T12:00:00-04:00","event_time_end_last":"2026-04-21T12:00:00-04:00","gmt_time_start":"2026-04-21 14:00:00","gmt_time_end":"2026-04-21 16:00:00","gmt_time_end_last":"2026-04-21 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Room 523A, TSRB","extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"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":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
