In our scheme, the analog signal is intensity and orthogonally modulated on a pair of co-propagated photonic links, i.e. one of the two intensity modulations has a bias angle which is 90 degree difference from the other. At the remote end, the analog signal can be linearly recovered by a digital signal processing based on the direct detections of the link pair. We experimentally demonstrate our concept through a piece of polarization maintained fiber (PMF), a polarization modulator (PolM), a polarizer, and the dual-channel wavelength division multiplexing (WDM) technology. The PMF, PolM, and the polarizer constitute an asymmetric mach-zehnder modulator (A-MZM), whose bias angle can be tuned easily by tuning the input optical carrier wavelength. Experiment results show 26.8 dB suppression of the third-order intermodulation distortion (IMD3) compared with the traditional quadrature-biased IM-DD link is achieved. Compared with the previously-reported linearized phase- or polarization-modulated, in-phase/quadrature demodulation (PM-IQD or PolM-IQD) analog photonic links, our scheme has the advantage that neither the highly-coherent optical local oscillation nor the precise polarization alignment is required in the remote end.","PeriodicalId":220534,"journal":{"name":"Microwave Photonics (MWP) and the 2014 9th Asia-Pacific Microwave Photonics Conference (APMP) 2014 International Topical Meeting on","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129545278","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 spectrally-sparse RF signal with unknown frequencies is modulated onto a highly chirped optical pulse. An optical channelizer slices the modulated pulse spectrum, which is equivalent to temporally sampling the RF waveform thanks to the dispersion-induced wavelength-to-time mapping. This serial-to-parallel conversion avoids the use of a high-speed detector and digitizer. Furthermore, compressive sensing with optical random demodulation is achieved using a spatial light modulator, enabling the system to capture the wideband multi-tone RF signal with a sampling rate far lower than the Nyquist rate. It is demonstrated that the temporal channelization system with a channel spacing of 20 GHz achieves RF spectrum sensing with a high resolution of 196 MHz. With an equivalent sampling rate of only 25 GHz, a 50-GHz broadband two-tone RF signal can be captured and reconstructed by the system thanks to compressive sensing with a compression ratio of 4.","PeriodicalId":220534,"journal":{"name":"Microwave Photonics (MWP) and the 2014 9th Asia-Pacific Microwave Photonics Conference (APMP) 2014 International Topical Meeting on","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126306191","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}
