Abstract

Direct measurements of the optical loss and gain of structures employing multiple layers of quantum dot lasers were presented. The layers of InGaAs quantum dots embedded in GaAs quantum wells along with adjustable thickness AlGaAs waveguides were used in the structures. The results revealed that the optical mode loss was independent of the number of quantum dot layers. It was also found that the quantum dot active regions proved to be useful for higher loss structures applications.
