Abstract

Ridge waveguides with smooth and vertical sidewalls are essential in photonic circuits. We have investigated waveguide realization with reactive ion etching of InP and InP-based structures using a SiNx. in a Ch/H2/CH4 chemistry in an rcp plasma. Depending on ICP power and RF power, etching rates can be obtained from 200 nmlmin up to > 2f.Lmlrnin. A maximum etching selectivity of InP vs SiNx of 12 was obtained at 2000 W of rep power. Deep etched waveguides, fabricated in an InP/InGaAsP double heterostructure, show typical losses of 2 dB/cm. This low value shows the potential of rep technique in the fabrication of photonic circuits.
