IMPORTANT: Please note that this is a graduate level course that is open to qualified undergraduate students. The course will be taught at the graduate level and all students will be expected to perform at this level. The only distinction between undergraduate and graduate students will be in the grading policy as previously outlined. A working knowledge of electromagnetic field theory and solid state devices is expected of all students in this class.

Why Study Photonics? WHAT ARE OPTICS AND PHOTONICS? OPTICS AND PHOTONICS ARE SPECIALIZED FIELDS OF PHYSICS AND ENGINEERING From fiber optics and telecommunications to medical imaging and cancer research, optics and photonics are advancing today’s critical technologies. Based on the science of light, optics and photonics are specialized fields of physics and engineering. These technologies are prevalent in almost every aspect of day-to-day life. From your computer screen to your cell phone and car headlights, optics and photonics are critical technologies that will continue to grow and enhance people’s lives.

Why Study Photonics? Medicine and Health Optics and photonics are utilized in numerous medical devices that help to save lives. Imaging equipment used for CAT, MRI and PET scans, as well as mammography, aid in the diagnosis of disease. Defense and Homeland Security Science and engineering research is the basis for many of the technologies currently being deployed to prevent and detect chemical, biological, radiological, nuclear and conventional terrorist attacks, as well as treat victims.

Why Study Photonics? Telecommunications Fiber optics connect the world through high-speed communications. In fact, the World Wide Web was developed by optics researchers. Today’s optics research is bringing higher-speed communications to our homes via fiber technology − enabling advanced data transmissions, like video streaming, and other broadband applications. Consumer Technologies Many of today’s “must-have” technologies such as digital cameras, high definition TVs and PDAs, were developed through optics and photonics research. Further research is expected to yield even more consumer products designed to enhance quality of life.

Why Study Photonics? An Example From Telecommunications
• Wider bandwidth than copper or microwave links. The bandwidth of optical fiber is about 25 THz
• Fiber attenuation is quite small, < 0.2 dB/km (The attenuation of coax is roughly 200 dB/km at 100 MHz, 625 dB/km at 1 GHz)
• Optical systems are smaller and lighter than microwave systems
• Greater security
• EMI immunity
• Availability of components
