While frequency combs were originally realized by mode-locked lasers, in recent years, their generation in high-quality-factor optical resonators has shown promise for light-weight, small-foot-print, robust, and power-efficient comb sources with larger repetition rates and in frequency regimes not available to mode-locked lasers. This thesis, focuses on ultrashort pulses based on microresonators which correspond to stable mode-locked frequency combs. The research described in this thesis has led to a novel synchronization model for mode locking in parametric frequency conversion and pulsed laser systems, a new method for deterministic generation of chip-based ultrashort pulses (dissipative Kerr solitons), and a robust design for broadband near-infrared frequency combs for rubidium-based optical clocks. The influence of higher-order dispersion on frequency comb generation and stability, and some limitations and advantages of different numerical approaches for theoretical comb studies are also explored.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Ultrashort Pulses in Optical Microresonators with Kerr Nonlinearity"}],"uid":"28475","created_gmt":"2016-12-05 21:51:20","changed_gmt":"2016-12-06 19:12:25","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-12-13T10:00:00-05:00","event_time_end":"2016-12-13T12:00:00-05:00","event_time_end_last":"2016-12-13T12:00:00-05:00","gmt_time_start":"2016-12-13 15:00:00","gmt_time_end":"2016-12-13 17:00:00","gmt_time_end_last":"2016-12-13 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"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":""}}}
