Recent advances in InP PICs

Abstract

Within the past couple of years InP-based Photonic Integrated Circuits (PICs) have become the subject of aggressive development for commercial applications primarily for the telecommunications industry. Chips with hundreds of photonic components carry live traffic in the field, but questions remain about cost/volume/performance tradeoffs, as well as the need for common integration platforms and/or foundry services. Research efforts have been influenced by these issues.
