Abstract

First-order and second-order gratings for the 1.55 μm wavelength InGaAsP laser have been fabricated by e-beam lithography on the InP substrate. The pattern is transferred into the InP substrate by wet chemical etching using HNO3:HBr:H2O and reactive ion etching using the gas mixture CH4:H2:Ar2. The experimental results have proven that a PMMA resist of 200 nm thickness can not only stand up to wet chemical etching but also to reactive ion etching.
