Abstract

We present an optimized grating formation process on InP substrates by using holographic lithography and a chemical etching. Process parameters associated with the developing and the etching were varied to ensure a reliable and reproducible fabrication condition. A quantitative experimental study of the variation of the grating shape with different fabrication conditions is presented and its optimization is discussed. 1.55 μm distributed feedback lasers were fabricated using an optimized grating formation process and lasing characteristics showed that the formed gratings are quite uniform and reproducible.
