Research output: Contribution to conferencePaperpeer-review


Mechanisms responsible for vertical cavity surface emitting laser degradation and failure were investigated using transmission electron microscopy and focussed ion beam sectioning techniques. It was found that the main cause of failure was the generation of complex dislocations dipole and loop arrays by non-radiative recombination enhanced mechanisms. Dislocations punched out due to oxide-induced strain or dislocations with origins in the substrate or surface appeared to act as nucleation sites for these complex arrays.
