Abstract
Fiber-induced optical feedback is studied by measuring the static properties of an oxide VCSEL as a function of fiber position and correlating the data to theoretical results using a vector mode-matching method which includes the fiber in the modelled structure. A novel method for estimating the linewidth enhancement factor in VCSELs is developed from the matching of theory and experiment. Two-mode competition in the VCSEL under feedback is also investigated.
