Intermediate carrier blocking layers (ICBLs) are introduced into multi-quantum well (MQW) active region of III-nitride multi-color LED to control the carrier injection distribution among the optically active quantum wells (QWs) with different emission wavelengths. Strong interdependence between ICBL parameters and active QW characteristics represents the main challenge for the full-color LED design and implementation. We show that ICBLs are essential elements of full-color RGB LED design requiring optimization both in material composition and doping level. Prototype ICBL-LED structure has been grown at Ostendo Technologies Inc. demonstrating tunable full-color operation.","PeriodicalId":425705,"journal":{"name":"2016 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"2018 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124281934","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 calculate the Purcell factor from a direct calculation of the local density of states from the band structure of the periodic unit cell. We compare this method with calculations of the Purcell factor obtained from the finite difference time domain (FDTD) calculations of the impedance of a dipole antenna located inside the structure. We show that we can study the Purcell factor in transverse electric (TE) and transverse magnetic (TM) polarisations by using electric and magnetic dipoles, we support our argument by analysing the dispersion relations of the structure.","PeriodicalId":425705,"journal":{"name":"2016 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126274989","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}

However, blue GaN-lasers still exhibit less than 40% power conversion efficiency, while GaN-based blue light-emitting diodes reach up to 84% This paper investigates non-thermal reasons behind this difference by comparative numerical device simulation. Fundamental material properties such as poor hole conductivity and high internal absorption are shown to make GaN-lasers inherently less efficient than GaAs-lasers.","PeriodicalId":425705,"journal":{"name":"2016 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"231 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114008481","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}
