We have demonstrated solderable VCSEL-based parallel optical modules which can minimize the foot print because it does not require any electrical pluggable interface. The optical module has been adopted to 100-Gb/s QSFP28 in commercialization. Here, we study how the optical modules can support network switches on the co-packaging architecture. Based on an assumption to simplify the co-packaging structure, we study the relationship between the width of optical module, the distance between optical module and switch ASIC, the length of substrate. As discussed, a data rate per channel should be 100 Gb/s or higher. A small 1.6-Tb/s or 3.2 Tb/s optical module might be suitable for a 51.2-Tb/s network switch.","PeriodicalId":339012,"journal":{"name":"2019 IEEE 2nd British and Irish Conference on Optics and Photonics (BICOP)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126167056","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 displacement along the sphere is perceived as a path that creates the well-known Berry's phase.

Our derivation is supported by the conjecture of Ritus-Nikishov by which field quantization might have its origin through artificial mechanism. In this manner, the classical counterpart might also provide an alternative path to arrive to pure Quantum Mechanics processes. Thus, in this paper we demonstrate that nonlinear Compton and the corresponding “pseudo” Feynman rules can also de extracted from a pure classical description. We present various spectra for simple and double Compton scattering that are in fully agreement with the existent Literature.","PeriodicalId":339012,"journal":{"name":"2019 IEEE 2nd British and Irish Conference on Optics and Photonics (BICOP)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128779251","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}

Such applications are anticipated to work every time without any fail which requires a constant data transmission. Hybrid communication systems are often used to provide reliable transmission, improve the performance of communication systems and provide better mobility to the end users. Contrary to the previous works on this area which discuss the implementation of relays between different communication links, the authors of this paper study the performance of cooperative visible-light communication (VLC) and radiofrequency (RF) communication systems with the presence of AF relay. The performance of the system under consideration is analyzed in terms of ergodic capacity. A mathematical method is exploited for this hybrid system to formulate the overall capacity of the proposed system by using the characteristics of the VLC and RF channels. The analytical results of the derived expression are verified by Monte Carlo simulations throughout this letter. The authors also investigate the effect of the several system parameters on its performance. The results revealed that the length of each link has a negative impact on the system performance. It was also found that the capacity of the integrated VLC/RF system is significantly improved by increasing the AF relay gain.","PeriodicalId":339012,"journal":{"name":"2019 IEEE 2nd British and Irish Conference on Optics and Photonics (BICOP)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133028446","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}
