The direct bandgap and the tunability of the relatively narrow bandgap with the ribbon's width renders them as suitable candidates for opto-electronic devices, especially for infrared applications. The performance of infrared photo detectors based on graphene nanoribbons is analyzed numerically, employing the non-equilibrium Green's function formalism.","PeriodicalId":120796,"journal":{"name":"2009 9th International Conference on Numerical Simulation of Optoelectronic Devices","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116108970","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 light extraction efficiency depends strongly on the photonic bandgap (PBG) position relative to a frequency (a/λ) and the depth of air hole for transverse electric (TE) and transverse magnetic (TM) polarizations. The maximum extraction efficiency was achieved when the frequency of a/λ was matched within PBG region, leading to about 29% (22%) higher than the conventional LED without photonic crystals for TE (TM) polarization. It is found that the polarization of light can be controlled by the a/λ in PC structure.","PeriodicalId":120796,"journal":{"name":"2009 9th International Conference on Numerical Simulation of Optoelectronic Devices","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133148354","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}

Simulation results show that the 1dB- and 3dB-bandwidth for the upstream channel are 115nm and 200nm, respectively. The proposed triplexer shows low insertion losses of less than 0.6dB and low crosstalks of less than −28dB for the two downstream bands, assuming that the waveguide width-error in the PLC fabrication is ±0.1µm.","PeriodicalId":120796,"journal":{"name":"2009 9th International Conference on Numerical Simulation of Optoelectronic Devices","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122122645","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}
