Integration density

Definition

Integration density refers to the degree of compactness with which optical components are arranged within photonic integrated circuits (PICs) or optical chips. A higher integration density indicates that more components can fit into a smaller area, enhancing functionality and efficiency while minimizing size. This is crucial for developing advanced optical devices that require complex functionalities in a compact form factor, thus enabling the scaling down of devices without compromising performance.
