Here, we describe a sensor modality utilizing guided mode resonances that can detect multiple markers for infection, that combines the sensor chip and spectrometer in a single chip and that can achieve a limit of detection as low as 1pg/ml. This performance is equivalent or better than laboratory-based techniques yet the sensor and instrumentation can be made entirely from low-cost components.","PeriodicalId":112265,"journal":{"name":"Active Photonic Platforms XIII","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130437877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We discuss the possible challenges and opportunities in forming optoelectronic devices in this platform and comment on the extension of this approach to other classes of materials.

Such an oscillator exhibits phase tristability, such that by reaching above the oscillation threshold it can take three different states with uniform phase contrasts. An analytically solvable second-order oscillator model is derived and the stability of the trinary phase states is proven through a Lyapunov function. The phase tristability of a three-photon down-conversion oscillator intrinsically emulates a classical trinary digit (trit). Such a trinary digit can be utilized for applications in unconventional computing.","PeriodicalId":112265,"journal":{"name":"Active Photonic Platforms XIII","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129496179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
