Popis: AlGaAs GaAs ridge waveguides with fundamental mode attenuation ≤ 1 dBcm−1 at a wavelength of 1.32 μm and channel widths of 4–4.5 μm are realized by ECR (Electron Cyclotron Resonance) plasma etching in BCl3/Cl2/Ar/N2 chemistries. The choice of both plasma chemistry and initial mask scheme (single layer photoresist or trilevel resist) has a significant effect on the attenuation losses.
