To meet the transmission rate demand, the recent pulse-amplitude modulation optical interconnects are discussed. To lower down the cost of the optical interconnects, low cost opto-electronic devices with strong bandwidth limitation and nonlinear distortion are employed. Moreover, the interplay between the fiber dispersion and square law photodetection leads to additional nonlinear inter-symbol interference. To handle the problem, various digital equalizers are introduced, which are reviewed in this paper.","PeriodicalId":177155,"journal":{"name":"2022 IEEE 7th Optoelectronics Global Conference (OGC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126941067","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}

Then, for solving the concentration monitoring problem of multi-channel microfluidics, the bimetallic anti-resonant fiber structure is proposed in this paper, which realize the multi-band microfluidic sensor of bimetallic reverse resonant fiber. Theoretical results show that the sensor achieves the surface plasma resonance (SPR) coupling of the core mode and the metal film at multiple bands of 1450 nm, 1650 nm and 1700 nm, then uses this feature to achieve refractive index sensing in three bands. The corresponding results have potential applications in the field of multimetallic microstructure fiber fluid sensing in the air core, and provide new ideas for the design of multi-band SPR resonance sensors, which are expected to be applied in the field of biochemical monitoring.","PeriodicalId":177155,"journal":{"name":"2022 IEEE 7th Optoelectronics Global Conference (OGC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125541925","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}

By analyzing the factors that affect the accuracy of monocular pose measurement, the research on the target layout of cooperative positioning is carried out. First, a sub-millimeter monocular spatial positioning simulation system is built, and the key components of the target layout are defined as Target Scale(TS) and Elevation Difference(ED); then, as the input, the 6DOF measurement accuracy of the monocular spatial positioning system under different conditions is obtained. The results show that the three-axis position accuracy is better than 0.5mm, and is affected by the positive correlation between the TS and the ED, and the axial variation is more significant. The three-axis attitude accuracy is better than 0.03° (1.8 arc seconds), which is greatly positive affected by the TS, and the axial pose is more robust than azimuth pose.","PeriodicalId":177155,"journal":{"name":"2022 IEEE 7th Optoelectronics Global Conference (OGC)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124732954","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 experiments show that the optimization of the above parameters is beneficial in improving the fluorescence intensity of this fiber light source from 1450 nm to 1700 nm. The concentration of erbium ions affects the luminescence efficiency of the fiber. It is demonstrated that the decrease of the fluorescence luminescence efficiency is due to the presence of a strong upconversion luminescence via experiments described in this paper. Finally, a high-brightness ultra-broadband light source with a full spectral width of 320 nm is obtained through a multi-parameter equalization method, and its 5db bandwidth near 1550 nm can reach 51 nm, and the output power of the light source can reach 1.95 mW.","PeriodicalId":177155,"journal":{"name":"2022 IEEE 7th Optoelectronics Global Conference (OGC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134570617","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 then applied this method to a 200 nm-thick SiO2-passivated concentric coupled GaP-OI resonator design for Kerr soliton frequency comb generation which gives rise to an anomalous dispersion span of 150 nm. The dispersion profile could be further optimized by changing the gap of the coupled rings, demonstrating the design flexibility.
