Abstract
Integrated optical devices composed of waveguides and microdisks emitting blue light were fabricated from ZnSe/(Zn,Mg)Se quantum well structures. Here we study the optical properties and photon guiding characteristics of such devices. The structures were fabricated by multi-step electron beam lithography and subsequent wet chemical etching. The transfer characteristic of photons through the waveguide was analyzed via spatial-resolved μ-photoluminescence spectroscopy. Spatial excitation of the microdisk revealed substantial overcoupling of photons from the microdisk into the waveguide.
