In SS-EONs, XT-aware and XT-avoided approaches are considered two main methods to deal with inter-core and inter-mode XTs. This paper addresses the question: which is the better choice for network operators between XT-aware and XT-avoided approaches to deal with inter-core and inter-mode XTs? Numerical results show that the XT-aware approach outperforms the XT-avoided approach in terms of resource utilization. On the other hand, the XT-avoided approach requires less computation time than the XT-aware approach.","PeriodicalId":363857,"journal":{"name":"2022 Workshop on Recent Advances in Photonics (WRAP)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129350752","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}

The presented feedback control system comprising a tunable laser, electronic frequency dividers, and other loop components enables the synthesis of a wide range of frequencies. The architecture provides the flexibility of using a wide range of RF sources and lasers for the generation of mm-waves, along with the advantage of a wide frequency tuning range. Experimental results also prove the feasibility of adapting the presented architecture for an mm-wave generation. This technique is an attractive solution for high frequency carrier generation for wireless communication (5G and beyond) and high speed clock generation in near-future electronic-photonic integrated circuits based signal processors.","PeriodicalId":363857,"journal":{"name":"2022 Workshop on Recent Advances in Photonics (WRAP)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116212151","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}

This method of surface enhanced Raman spectroscopy (SERS) has paved the way for these plasmonic nanostructures to be used as potential SERS substrates in applications like bio-sensing, diagnostics and other applications. In order to optimize the SERS enhancement, the plasmon resonance of the nanostructures needs to be tuned. The usage of alloy nanoparticles has been an efficient method to achieve this. In this paper we study Ag-Cu alloy nanoparticles with Janus morphology and explore the possibility of tuning the plasmon resonance in order to utilize the nanostructures for dual wavelength SERS applications.","PeriodicalId":363857,"journal":{"name":"2022 Workshop on Recent Advances in Photonics (WRAP)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126096035","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}
