At PhotonFirst we develop integrated photonics-based sensing solutions for a broad range of applications and markets, with an emphasis on Fiber Bragg Grating (FBG) monitoring applications. The way in which photonic building blocks are combined and connected is vital for the performance, reliability, footprint, manufacturability, and applicability range of the solution. When targeting a broad application base such as sensing, a modular and holistic approach is key. In our contribution we provide examples of PIC-based hybrid integrated solutions specifically developed for sensing applications and use these to highlight the specific sensing requirements and challenges that come with integration.
