Abstract :
We have demonstrated that independent control of three band-gaps across an InP-InGaAs-InGaAsP QW wafer can be achieved by a two-stage sputtered silica intermixing processes. This will be used for optimisation of the performance of optical switches which consist of passive components, modulators and amplifiers
