An electromagnetic-field simulator has thus shown that the width of the LN crystal substrate is the main impediment to achieving high frequency and sensitivity; based on this result, we created four prototype 10-GHz band lumped-constant LN optical modulators, and evaluated their performance. As a result, we measured a resonant frequency of about 10.1GHz with an LN crystal substrate that was 1.4 mm wide and 0.3 mm thick, and achieved a 20dB CNR. This provided an optimistic outlook on the possibility of achieving a high-sensitivity LN optical modulator operating in the 10 GHz band, which is the highest allocated frequency range.","PeriodicalId":220534,"journal":{"name":"Microwave Photonics (MWP) and the 2014 9th Asia-Pacific Microwave Photonics Conference (APMP) 2014 International Topical Meeting on","volume":"158 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":"122032907","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}

It is found that the signal evolution in the RFS loop is not just simply the same as the straight-line transmission, but the resonance effect of the loop will dramatically affect the property of the generated OFC. Keeping the frequencies of tones away from the resonance frequencies of the loop as much as possible would avoid the phases of the tones synchronously locked, which could greatly decrease the temporal peak power of the generated OFC. This will relieve the influences caused by the instantaneous effect of erbium doped fiber amplifier (EDFA) and fiber nonlinearity, which, in return, would contribute to expand the spectral range of the OFC without much quality degradation. Finally, as an experimental verification, by adjusting the length of the RFS loop to minimize the resonance, a record 100-tone OFC with 10GHz frequency spacing by just single RFS loop is also successfully realized.","PeriodicalId":220534,"journal":{"name":"Microwave Photonics (MWP) and the 2014 9th Asia-Pacific Microwave Photonics Conference (APMP) 2014 International Topical Meeting on","volume":"87 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":"133822087","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 proposed system, the time reversal is realized by the LCFBG that is operating in conjunction with a polarization beam splitter (PBS) to enable a triple use of the LCFBG with the signal entering the grating from either the long or the short wavelength end. Since the LCFBG has a wide bandwidth and is used three times with exactly complementary and identical dispersion, the implementation of broadband and precise microwave time reversal is ensured. A theoretical analysis is performed which is validated by an experiment. The time reversal of a 5-GHz microwave single with a bandwidth of 3.3 GHz and a time duration of about 0.7 ns is demonstrated, which is, to the best of our knowledge, the fastest microwave time reversing system ever reported.","PeriodicalId":220534,"journal":{"name":"Microwave Photonics (MWP) and the 2014 9th Asia-Pacific Microwave Photonics Conference (APMP) 2014 International Topical Meeting on","volume":"7 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":"121196214","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}
