Optical elements such as light-pipes and lenses allow physical coupling of the PICs with the external environment. Optimal design is a critical part of the design for manufacturing (DFM) process and can deliver impact in terms of increasing both brightness of the source and signal to noise ratio of the optical sensor. One of the biggest challenges in photonic integrated circuits (PICs) is to design a system that continues interacting with the external environment without a loss of quality over time.
