Static and Dynamic Transverse ModeCharacteristics of Vertical-CavitySurface-EmittingSemiconductor LasersPh.D. ThesisbySafwat William Zaki MahmoudM.Sc. in Physics, El-Minia, EgyptWork performedat the Department of Optoelectronics,Faculty of Engineering Science,University of Ulm, GermanyDean of the Faculty: Prof. Dr.-Ing. H.J. P eidererst1 Referee: Prof. Dr. rer. nat. K.J. Ebelingnd2 Prof. Dr.-Ing. H. SchumacherOral examination: 10. June 2002PrefaceThis work was supported by the Egyptian Ministry of Education and Scientiflc Research.As a doctoral student at the Faculty of Science, El-Minia Univeristy, Egypt, I was nom-inated for a scholarship from the missions department which belongs to this Ministry.After a series of examinations, I was selected for an abroad scholarship to do my Ph.D.researchinthefleldofsemiconductorlasersandtheirapplications. IchoseUlmUniversity,Germany since it is one of the leading European centers in optoelectronics. I acknowledgethe contributions from the stafi of these organizations either in Egypt or in the EgyptianEmbassy in Germany.ThisworkhasalsobeenpartiallysupportedbytheDepartmentofOptoelectronicsofUlmUniversity under a project funded by the German Federal Ministry of Education and Re-search. During my studies, the department has provided the best research environment.I wish to express my deepest gratitude to Prof. Dr. K.J.
