The study explores the characteristics of the 2D perovskite, focusing on harnessing the optical Stark-induced energy shift in the polariton branches. The polaritonic coupler, which has a single input and two divergent outputs, is subjected to an external optical Stark pulse, dynamically guiding polaritons between the input and outputs. The research focuses on examining the controllability of the polaritonic coupler through the polariton coupling ratio, highlighting the regulatory role played by the optical Stark effect in this dynamic process. In-depth analyses of the spatial distribution and time evolution of polaritons within the coupler reveal that the optical Stark pulse effectively regulates the polariton coupling ratio, realizing a programmable coupler. This investigation not only advances the fundamental understanding of polariton dynamics within 2D hybrid organic-inorganic perovskite microcavities but also demonstrates the potential for developing optically controlled integrated photonic devices.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142021630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The underlying mechanism is universal to all optical filters, whereas here, simulations were based on micro-ring resonators. Investigation revealed that the photonic neural node can be tuned to support a wide variety of continuous activation functions that are relevant to the neural network architectures, such as the sigmoid and the soft-plus functions. The proposed photonic node is numerically evaluated in the context of time delayed reservoir computing (TDRC) scheme, targeting the one-step ahead prediction of the Santa Fe series. The proposed phase to amplitude TDRC is benchmarked versus the conventional amplitude based TDRC, showcasing a performance boost by one order of magnitude.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
