A single Remote Antenna Unit (RAU) supported by Radio-over-Fiber transport is used to transmit multiple 60GHz band signals to various users located at different spatial locations using the beamsteering characteristics of a Leaky Wave Antenna (LWA). Error Vector Magnitude analysis has been performed for each user signal up to a maximum of seven users per RF chain with wireless transmission over 2m. A performance comparison for different user-signal frequency spacings has been provided to understand the limitations of the system and results show that the proposed system design with the LWA performs better than systems using waveguide and horn antenna transmitters. A realization to double the number of served users is also presented which shows that up to 10 users can be served using half region of the LWA, with each user transmitting 1Gb/s data rate, delivering an aggregate data rate of 10Gb/s.","PeriodicalId":146799,"journal":{"name":"2018 International Topical Meeting on Microwave Photonics (MWP)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116603837","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 system therefore becomes complicated and expensive. In this work, we present a novel single-wavelength microwave photonics transversal filter design in the coherent regime using a single multimode fibre. Filter taps are generated from spatial modes excited by multiple narrow optical beams with different incident angles. Therefore, optical interference is eliminated due to space demultiplexing. Time delays between filter taps are obtained due to large modal dispersion and can be simply tuned using spatial slots. In a proof-of-concept experiment, a modal dispersion enabled optical delay line module for a two-tap microwave photonic transversal filter has been demonstrated with avoided optical interference.","PeriodicalId":146799,"journal":{"name":"2018 International Topical Meeting on Microwave Photonics (MWP)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127506096","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}

In the scheme, a signal receiver exploits an optical I/Q architecture fed by two free-running lasers to filter and down-convert to baseband the incoming RF signal. At the same time, a reference receiver acquires the phase-noise of the two free-running lasers by heterodyning them with an optical frequency comb. Then, a digital feed-forward algorithm utilizes the heterodyning signal to extract the differential phase noise between the two free-running lasers so that to cancel the phase noise that the lasers sources introduce to the baseband signal. Moreover, the scheme is effectively divided in a central unit and a remote-antenna module in order to provide improved remoting capability through fiber optic links. An experiment demonstrates low phase noise operation in an RF input range of 0-50 GHz, only limited by the available laboratory equipment. Photonic integration of the scheme will reach high environmental stability and chip-scale footprint, targeting the challenging requirements of next-generation electronic support measures systems.","PeriodicalId":146799,"journal":{"name":"2018 International Topical Meeting on Microwave Photonics (MWP)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134343320","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 focus mainly on the beatnote phase noise of the two orthogonally polarized modes emitted. Within the framework of coupled rate equations, we show that the phase noise spectrum of the beatnote is well described by considering both the phase–amplitude coupling and the thermal effects. The spearhead of this study consists in first theoretically evidencing reduction strategies for the phase noise beatnote by optimizing the physical parameters of the model and then experimentally demonstrating its feasibility by using two in-phase fully–correlated beams pumping each mode separately. Possible ways to decrease the intensity noises are also identified.","PeriodicalId":146799,"journal":{"name":"2018 International Topical Meeting on Microwave Photonics (MWP)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127198159","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}
