Grading Policy:

8/20/14


Grading Policy: Collected homework is due one week after it is assigned. The deadline is 5:00 pm of the day it’s due. After 5:00 pm, and up to one day late, there is a 25% reduction in grade. Two days late, a 50% reduction in grade. Three days late, a 75% reduction in grade. More than three days late, homework not accepted. If your homework solutions are unclear you might be called in for clarification. NEATNESS COUNTS! Electronic submission are acceptable.

8/20/14


Grading Policy: On all work submitted, neatness and clarity of presentation (i.e., professionalism) counts. Plots and graphs must be done using a computer. A deduction in for a poorly prepared submission will be made at the discretion of the instructor. The allowed time for quizzes will vary based on complexity. The time limit on quizzes will be STRICTLY ENFORCED. When time is up, all writing MUST STOP. Failure to do so will result in a grade of zero for that quiz. There could be more than one short quiz per week. A quiz might be repeated if the results so warrant. Missing classes does not excuse you from knowing what was covered. If you are absent, ask your classmates what was covered that day. Material discussed in class is potential quiz material. Some quizzes will be open-note or open-book, some will not. Be prepared. All this said, my goal is for the course to be fun for both of us.

Possible Topics for Graduate Student Presentation:

Magneto-Optics Photonic Crystal Fibers Fiber Bragg Gratings Waveguide WDM devices Photometers Electroabsorption Modulators FBG Vibration Sensing Photonic Metamaterials Single-photon Detectors Coupling of Light in a Fiber Semiconductor Optical Amplifiers Optical Coherence Tomography Optical MEMS Microring Resonators Photoconductivity Quantum Dot Lasers

Presentations should minimally address the following topics:

What is the topic of the paper? Briefly explain the theory of operation. What are the primary uses? What are the limitations? To where is the technology moving?

8/20/14


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 some basic knowledge of 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.

Optical Spectrum

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

Why Study Photonics? An Example From Telecommunications Consider a typical communications system: What would you need to do this? What problems would you expect to encounter? Discuss this among yourselves.
