The course aims to give an introduction into the field of integrated optics.
Integrated optics is expected to become one of the key enabling technologies of the 21st century, helping to overcome the bottlenecks faces by current electronics. Several decades ago, optical fibers revolutionized the communication field, providing affordable connectivity between people in different parts of the world. A prime example is the wide spread of high-speed internet and mobile communications which was possible thanks to optical fiber technology. Integrated waveguides are on-chip versions of optical fibers. First proposed in the 1960's, integrated optical circuits are analogous to electronic integrated circuits. The main difference is that the information is processed in the form of "light" instead of by electrical signals, enabling therefore much higher transmission speed and processing capabilities. By selecting the correct set of materials, waveguiding structures, that confine and route light with dimensions in the micrometer and even nanometer scale, can be integrated on a chip. In this course, you will learn the foundations of the field “integrated optics" and you will acquire the necessary theoretical and practical skills required to design various integrated photonic devices. In lecture format, the basic principles covering the theory of planar waveguides, basic structures, non-linear optics, materials and technology, as well as an introduction into numerical methods and different commercial software tools will be discussed in the first half of the course. The theoretical knowledge acquired will form the basis for the solution of a number of practical assignments, executed using commercial design tools. During the final assignment you will perform the complete design and optimization of an integrated photonic device. The course evaluation is based on the student's written reports (exercises and final report). The following basic and modern topics, relevant for optical sensors, on-chip lasers and optical amplifiers, and telecommunication, will be treated:
- Theory of planar waveguides,
- Integrated Optics Basic structures,
- Beam Propagation Methods,
- Photonic Crystals, Plasmonic waveguides, Optical filters, Active Devices,
- Materials and technology,
- Fields of application include telecommunication, on-chip photonic devices for medical applications and optical sensors.
