In addition, these devices can take advantage of the widespread existing infrastructures realized on G.652 Standard Single Mode Fibers (SSMF) to develop low-cost RoF connections while remaining transparent for the presently transmitted Fiber-To-The-Home services, which exploit the second and third optical windows. Within this context, the use of simple butt-coupling between FW-VCSELs and SSMF should be a desirable feature, which however is theoretically exposed to possible drawbacks of poor efficiency and two-mode propagation effects. Through a detailed experimental activity referred to commercial high-performance multi- and single-mode FW-VCSELs, it is shown how to optimize their butt-coupling configuration to SSMF reducing the mentioned drawbacks and consider this solution suitable for 5G-and-beyond low-cost Green RoF applications.","PeriodicalId":127318,"journal":{"name":"2022 IEEE International Topical Meeting on Microwave Photonics (MWP)","volume":"10852 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122331474","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 FTnet is a new deep learning network, which replaces the self-attention mechanism of the Transformer encoder with a Fourier layer. The FTnet-based digital demodulator can directly recover corresponding bitstreams from the impaired receiving signal, which replaces a series of digital signal processing in the RoF traditional digital demodulator, including down-conversion, matched filter, downsampling, phase offset compensation, equalization, decoding, etc. A 10 GHz 16/64QAM 2 Gsym/s 25 km RoF transmission system is established to verify the proposed method. The experimental results show that the receiving sensitivity for 16QAM and 64QAM systems with the proposed demodulator can be improved by 1 dB and 5 dB respectively compared to traditional digital demodulator with LMS equalizer under a bit error rate limit of 3.8×10−3.","PeriodicalId":127318,"journal":{"name":"2022 IEEE International Topical Meeting on Microwave Photonics (MWP)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131954231","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 ability to modify the optical and electronic properties of ITO makes this a novel material with unlimited possibilities to outperform current tunability mechanism. In this paper, we demonstrate the use of the quasi-metallic feature of ITO as an active microheater control for realizing a tunable MWP phase shifter.

The LFMP modulates the interrogation light, creating the optical sideband that sweeps through the resonance rapidly. By using the optimized DC bias point, the resonance spectral dip with arbitrary characteristics can be transformed into the zero point in the temporal envelope of the transmitted LFMP, hence providing improved interrogation resolution of the resonance shifts caused by environmental changes. The proposed scheme was implemented with a microdisk resonance for temperature sensing, where up to 20-fold interrogation resolution improvement was demonstrated by tuning the DC bias voltage to the optimum. The interrogation speed is 500 kHz, which can be further improved by using a shorter repetition period and pulse width.","PeriodicalId":127318,"journal":{"name":"2022 IEEE International Topical Meeting on Microwave Photonics (MWP)","volume":"167 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116695235","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}
