Photonic integrated circuits are crucial for a wide range of modern technologies. While most current integrated circuits are based on glass, sapphire-based platforms offer exceptional potential due to their broadband transparency, hardness, and stability in extreme environments. These properties make them ideal for applications in space, aerospace, and other demanding fields.
This webinar explores the fabrication of sapphire photonic devices using adaptive optics-assisted femtosecond laser direct writing. Low-loss and polarization-independent devices, including beam splitters and evanescently coupled arrays, were demonstrated at both 780 nm and 1550 nm. The process is highly efficient and scalable, paving the way for the compact integration of multiple photonic functions on a sapphire platform.
