In the realm of photonics, the integration of multiple optical devices onto a single substrate holds immense promise for a wide range of applications. This revolutionary approach, known as photonic integration, offers remarkable advantages, including reduced size, cost, and power consumption. Among the major integration technologies in photonics, two stand out: indium phosphide (InP)-based photonic integration and monolithic silicon photonics. Each technology has its unique strengths and weaknesses.
