For InP-based photonic circuits and other applications, it is often desired that the etch profiles are vertical and smooth so that light scattering losses are minimized. Cl2/N2 or Cl2/Ar ICP etching of InP at 200C sample temperature is often used to create smooth, high aspect ratio structures. However, these etches often produce micro-...
