We analyse the band structure of strained InGaBiAs alloys and quantify their potential for the development of mid-infrared semiconductor lasers. In addition to identifying the permissible growth combinations for this class of laser structures, we perform a comprehensive analysis of the performance of a series of ideal laser structures. We investigate the variation of key material and device parameters on the alloy composition, QW thickness and epitaxial strain, and on this basis identify optimised laser structures for emission across the 3-5 μm wavelength range. Our theoretical analysis suggests that InP-based dilute bismide alloys are an extremely promising candidate material system for the development of highly efficient and temperature stable laser diodes operating in the mid-infrared, and also that this class of laser structures is highly compatible with existing InP-based device architectures.","PeriodicalId":425705,"journal":{"name":"2016 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124206500","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 spontaneous emission peak begins to decrease when the boron composition exceeds a critical value. The critical value is found to increase rapidly with decreasing the absolute value of the spontaneous polarization constant. In addition, the light intensity is reduced with decreasing spontaneous polarization. However, the spontaneous emission peak of BAlGaN/AlN QW structures is found to be greatly improved with the inclusion of the boron, irrespective of the spontaneous polarization. Hence, we expect that BAlGaN/AlN QW structures can be used as a high-efficiency light source for optoelectronic applications in ultraviolet spectral region.","PeriodicalId":425705,"journal":{"name":"2016 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"13 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":"121954080","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}

This growth is in no small measure related to the success of the quantum cascade laser (QCL) which has established itself as one of the most promising radiation sources at terahertz frequencies [2]. The appeal of these novel semiconductor lasers stems from their compact size, broad spectral coverage (~ 1-5 THz), and high output powers [3].
