| Popis: |
The excellent performance of vertical-cavity surface-emitting lasers (VCSELs) in the wavelength range below 1mm is largely due to the superior properties of the epitaxially grown AlAs-GaAs distributed Bragg reflectors (DBRs). For long wavelength VCSELs there is no material combination for Bragg reflectors with properties as good as AlAs-GaAs. Therefore we decided to explore the possibility of employing InP and oxidized InAlAs as high and low index material in highly reflecting Bragg mirrors at a wavelength of 1 55mm. Here we describe initial results on the oxidation of InAlAs layers. |
