Standardized Process Could Revolutionize Photonic Integration
A generic foundry approach could result in a dramatic cost reduction for production of PICs for a variety of applications. A revolution is coming in photonic integration technology, facilitated by the introduction of generic foundry processes: highly standardized photonic integration processes that enable realization of a broad range of application-specific photonic integrated circuits (ASPICs) from a small set of basic building blocks. This will lead to a dramatic reduction of the developmen...
