ABSTRACT
A novel method for studying the dependence of scattering loss on guide structure in integrated-optic semiconductor rib waveguides is presented. The results provide a simple experimental test for determining the nature of the scattering loss. Differences in scattering due to changes in epilayer structure and ribwall slope are also investigated.

    Tunable twin-guide laser diodes with improved lateral current injection structure and high output power are reported. By optimising the doping profile of the n-InP layer laterally surrounding the buried stripe, inherent leakage currents are effectively minimised. Thereby, the carrier injection...
