The different crystal orientations of these layers lead to different polarization induced internal fields and transition energies. The simulation approach accounts for these effects by including the calculation of strained band edges and piezo potentials and provides a self-consistent model for the coupled 3D bulk and 2D quantized structure. The simulator is targeted to a comprehensive analysis of luminescence including the spatial variation of transition energies and carrier densities.","PeriodicalId":6780,"journal":{"name":"2021 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"117 1","pages":"91-92"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79753035","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}

Degradation of the performance with increased area is observed and analyzed in terms of the power loss density concept. The equivalent circuit model is used to verify that a change in power loss density (or RSA) can have a strong influence on device performance. The limited sheet resistance of ITO is found to be one of the major limiting factors when the area of the cell is increased. The effective series resistance of the ITO film can be minimized by integrating metal grids and the improvement is analyzed using a power loss density analysis. By integrating metal grids onto ITO, the series resistance could be reduced significantly yielding improved performance.","PeriodicalId":6780,"journal":{"name":"2021 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"52 1","pages":"67-68"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85553379","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}

Deeply etched mesas can prevent this lateral diffusion, but may themselves contribute to a degradation of optical gain if the sidewalls are not effectively passivated. Simulation results considering the effects of surface recombination velocity (SRV) at the edge of the etched active layers indicate that SRV must be reduced below approximately 105 cm/s in order for deep etch designs to provide benefit. Very few experimental studies quantify the efficiency of GaN surface passivation in terms of SRV. Further experimental studies are required to better assess the viability of deep etch MQW laser designs.","PeriodicalId":6780,"journal":{"name":"2021 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"72 1","pages":"51-52"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86288113","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 method, a Gaussian pulse is represented by a 2×2 complex Q-matrix and an optical element is represented by a 4×4 real K-matrix. This formalism models pulse compressors and performs full spatio-temporal analysis. Additionally, this formalism allows for uncertainty and sensitivity analyses of the compressors/stretchers. While being simple to implement numerically, this method is computationally much faster than the other equivalent approaches, such as use of Wigner matrices and Wigner functions.","PeriodicalId":6780,"journal":{"name":"2021 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"39 1","pages":"115-116"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80514345","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}
