| Abstract | In the present paper, the comprehensive self-consistent VCSEL physical model is used to analyse excitation of successive transverse cavity modes in oxide-confined (OC) vertical-cavity surface-emitting diode lasers (VCSELs) using the double intra-cavity-contacted 5-λ-cavity double-quantum-well GaAs-based GaInNAs/GaAs OC VCSEL emitting the 1.3-µm radiation as a typical VCSEL example. As expected, many inter-related physical phenomena occurring within a VCSEL volume have an impact on the mode excitation, e.g. the current spreading between both annular contacts and the central active region, the carrier injection into the active region and radial diffusion within it, creation of optical standing waves within the VCSEL cavity, the heat-flux generation and extraction, creation of the active-region gain profiles, the radial wave-guiding mechanism, penetration passive areas by the mode optical field, spatial hole-burning effect etc. Therefore, for any VCSEL design, an analysis of its mode selectivity requires the fully self-consistent comprehensive simulation of all the above important phenomena together with numerous important interactions between individual physical processes, as it has been done in the present paper. Over-simplified theoretical models may lead to faulty results. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
