Deep-space optical communications have been proposed to increase data bandwidths and reduce the size, weight, power, and cost of legacy electrical systems. Integrated silicon photonics technology has become a contender to realize these space systems due to their rapid advancement in terrestrial systems over the past decade. However, little is known about this technology\u0026#39;s response to and system-level impact of single-event phenomena. To better understand the limitations of silicon photonics for space applications, several experiments that emulated single-events were conducted on various integrated components. In the first work, optical single-event transients were induced in an integrated waveguide by a two-photon absorption process. The results reveal that an optical signal can experience temporal absorption during an event that generates a dense cloud of carriers within its path. In the next work, a single-event transient that originates within the electronics of a Mach-Zehnder modulator is shown how it propagates to the modulator\u0026#39;s optical output. These propagation results indicate that the effect of electrical single-event radiation can be suppressed using clever design techniques. The proposed research will continue the single-event analysis with photodiodes, analyze the effects of single-event radiation in optical communications through bit-error probabilities, and compare single-event radiation induced by two-photon processes and heavy-ion bombardment within integrated waveguides.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Single-Event Radiation Response in Silicon Photonic Components and Systems"}],"uid":"28475","created_gmt":"2021-04-21 09:40:09","changed_gmt":"2021-04-21 09:40:09","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-04-26T16:30:00-04:00","event_time_end":"2021-04-26T18:30:00-04:00","event_time_end_last":"2021-04-26T18:30:00-04:00","gmt_time_start":"2021-04-26 20:30:00","gmt_time_end":"2021-04-26 22:30:00","gmt_time_end_last":"2021-04-26 22:30:00","rrule":null,"timezone":"America\/New_York"},"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":""}}}
