Abstract

A novel process of wafer bonding between InP and a garnet crystal (Gd ₃Ga₅O₁₂, CeY₂Fe₅O ₁₂) based on O₂ plasma surface-activation and low temperature heat treatment is presented. The O₂ plasma assisted wafer bonding process was found to be very effective in bonding of InP and Gd ₃Ga₅O₁₂, providing good bonding strength and hydrophilicity as well as no voids in the interface, which is crucial for fabrication of an integrated optical waveguide isolator. The isolation ratio of an integrated optical waveguide isolator fabricated by the O₂ plasma assisted wafer bonding process was obtained to be 2.9 dB.
