Investigation of dielectric cap induced intermixing of InxGa1−xAsyP1−y/InP quantum well laser structures by photoreflectance and photoluminescence
Abstract
The quantum well intermixing (QWI) of 1.55 μm laser structure through thermal treatment, utilising various cap layers, has been investigated by both photoluminescence (PL, emission-like) and photoreflectance (PR, absorption-like) experiments. A blue shift of the QW ground state transition has been observed for post-grown-modified laser structures. The influence of the cap stoichiometry on QWI has been analysed. It has been found that the …
