  • Abstract
    We have fabricated two-dimensional photonic crystals in InP-based materials with Cl2-based inductively coupled plasma etching. To obtain vertical sidewalls, we employ sidewall passivation through addition of N2 or O2 to the plasma. With the Cl2O2-process we are able to etch 3.2 μm deep holes that have nearly cylindrical shape in the upper 2 μm. The first optical results illustrate the feasibility of our approach, showing over 30 dB transmission reduction in the ΓK-stopband.
