To realize matched filtering, the filter should have a spectral response that is matched to that of the input pulse, which is implemented in this paper using a photonic system that consists of an optical single-sideband (SSB) modulator and a fiber Bragg grating (FBG). The FBG is designed to have a spectral response which is transferred to the spectral response of the microwave filter via SSB modulation and heterodyne detection at a high-speed photodetector. A theoretical investigation on the microwave filter design and the chirped microwave pulse compression is developed. Theoretical analysis on the implementation of three different forms of microwave matched filters, including a classical complex matched filter (CMF), a phase-only filter (POF) and a modified inverse filter (MIF), is presented. A comparison between the filters against the performance measures for a linearly chirped microwave signal compression is provided.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126431720","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 multiple quantum well structure consists of 20 periods of 18 nm QWs interleaved by 80 nm barriers with an Al alloy content of 2%. We measured the following performance characteristics: dark current, responsivity, and spectral response. A responsivity of 13 mA/W at an electric bias of 40 mV and an operating temperature of 3 K was obtained with a peak response close to the designed detection frequency. The dark current density was a few muA/cm2 and was limited by thermally assisted tunneling through the barriers. We looked also at possible designs to optimize the devicepsilas performance.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125175944","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 this work, optical hydrophone sensors based on single mode straight - cleaved fibers and down-tapered coated fibers with sensitive dimensions of less than 10 mum have been reported. Thinly gold coated optical fiber sensors demonstrated a higher sensitivity and bandwidth performance than straight cleaved uncoated and down-tapered uncoated. The statistical analysis clearly indicates that the gold coated fibers with thickness of 30 nm provide a 26 dB improvement in sensitivity over that of the uncoated straight cleaved fibers, raising the overall sensitivity of the fiber optic hydrophone sensor to a value of -245 dB re 1 V /muPa (unprecedented 0.56 V/ MPa). Broadband testing of these sensors with a 10 MHz acoustic tone burst further indicates that the bandwidth of gold coated fiber sensor is as high as 60 MHz. Amplified optical source intensity noise limits the current intensity detection system up to 60 MHz.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116096060","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}
