Increased Component Density Plants Hurdles on the Road to Scaling the Production of PICs Sep 27, 2022 — When CEO Iñigo Artundo’s company began providing engineering solutions for photonic integration in 2011, the typical photonic integrated circuit (PIC) had five to 10 components. Today, VLC Photonics is seeing far more complex photonic chips, each containing a growing number of optical components. For example, highly complex PICs can now accommodate more than 1000 optical components on a single, monolithic, indium phosphide (InP)-based chip. Increased component density is a trend...
