Introduction to Photonic Materials and Device Design

Light is the future of high-speed communication, sensing, and computing, but manipulating it requires a solid grasp of physical materials and device physics. This course guides you through the foundational concepts of photonics, from how light behaves in different media to how modern optical components are designed and fabricated. You will transition from understanding basic optical physics to analyzing complex photonic systems, including waveguides, light sources, and detectors. By studying core materials like semiconductors, dielectrics, and polymers, you will gain the skills needed to conceptualize modern microphotonic circuits. What you'll learn: - Understand the core principles of ray optics, electromagnetic waves, and guided wave propagation. - Analyze the properties of semiconductor, dielectric, and polymer materials used in optical devices. - Explore the design and operation of LEDs, semiconductor lasers, photodetectors, and optical modulators. - Examine modern fabrication techniques like thin-film deposition, etching, and silicon photonics integration. - Study the foundations of photonic crystals and co-packaged optics for high-speed data transmission. - Practice evaluating optical systems through written design challenges and analytical exercises. The course begins with essential terminology and the physics of light-matter interactions before moving into specific device architectures and modern manufacturing processes. You will progress systematically from basic material science to integrated optical circuit design. This text-based course is designed for beginners, engineering students, and professionals looking to transition into optical technologies. No prior background in photonics is required, though a basic understanding of physics and algebra is helpful.
