The benefits of OCT precoding in SISO-, MIMO-VLC, and the inherent reason of performance improvement, will be discussed. In addition, comparisons of the existing solutions to combat the limited modulation bandwidth of VLC systems will be presented. Potential applications of the OCT precoding in other systems will be given.","PeriodicalId":6655,"journal":{"name":"2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR)","volume":"47 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90377485","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}

Silicon nitride (SiNx) grating coupler suffers from lower efficiency due to the relative low material refractive index. The efficiency of SiNx grating coupler can be improved by using high reflectivity silicon grating reflectors underneath. However, such silicon grating reflector requires several fabrication steps, including lithography, etching, high precision alignment (HPA), and chemical mechanical polishing (CMP). In this work, we demonstrate an easy-to-fabricate SiNx grating coupler only requiring a single patterning step without the need of HPA and CMP. A coupling coefficient of −2.5 dB and 1-dB-bandwidth of 65 nm have been experimentally measured.","PeriodicalId":6655,"journal":{"name":"2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR)","volume":"79 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83796188","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}

A numerical model based on transfer matrix method is utilized to simulate the performance of this device. The coupling between the microring resonator and the Fabry-Pérot resonator formed by nanoholes gives rise to the dual-band optical filtering spectrum. In our experiment, a single microring resonator embedded with nanoholes was fabricated on a commercial 220-nm-thick-top-silicon silicon-on-insulator (SOI) platform. Good performance was achieved with measured extinction ratio of 9 dB, insertion loss of lower than 1 dB, and quality factor of 11900. Both experimental and simulation results are in good agreement.","PeriodicalId":6655,"journal":{"name":"2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR)","volume":"1 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79460921","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}

However, in order to realize such cascaded metasurfaces, a key issue is to achieve high precision alignment of the structures in each layer usually with large distance in between. Here we propose and experimentally confirm two schemes based on optical alignment and electron-beam alignment respectively to align the frontside and backside of a wafer in order to realize cascaded metasurfaces on these two sides. Except for cascaded metasurface structures, these approaches may also have a wide range of applications in need of other cascaded structures for specific functionality.","PeriodicalId":6655,"journal":{"name":"2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR)","volume":"1 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80200105","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}
