Integrated optics is a field of research and technology that involves the integration of different optical components, such as lasers, waveguides, and modulators, onto a single substrate, such as a silicon chip. This allows for the creation of compact and efficient optical systems that can be used for a variety of applications, including telecommunications, sensing, and data processing. Integrated optics has the potential to revolutionize the way we manipulate and transmit light, making it an important area of research in the field of photonics.
