Household Energy Conservation and Efficiency

(Complete Item Description)

Abstract:: Students complete three different activities to evaluate the energy consumption in a household and explore potential ways to reduce that consumption. The focus is on conservation and energy efficient electrical devices and appliances. The lesson reinforces the relationship between power and energy and associated measurements and calculations required to evaluate energy consumption. The lesson provides the students with more concrete information for completing their culminating unit assignment.

LASER

(Complete Item Description)

Abstract:: What is the difference between an LED and a solid state laser? There are some differences, but both devices operate on the same principle of having excess electrons in the conduction band of a semiconductor, and arranging it so that the electrons recombine with holes in a radiative fashion, giving off light in the process. What is different about a laser?

Photonic Materials and Devices, Spring 2004

(Complete Item Description)

Abstract:: Optical and optoelectronic properties of semiconductors, ceramics, and polymers. Electronic structure, refractive index, electroluminescence, electro-optic and magneto-optic effects, and laser phenomena. Microphotonic materials and structures; photonic band gap materials. Materials design and processing for lasers, waveguides, modulators, switches, displays and optoelectronic integrated circuits. Alternate years. This course covers the theory, design, fabrication and applications of photonic materials and devices. After a survey of optical materials design for semiconductors, dielectrics and polymers, the course examines ray optics, electromagnetic optics and guided wave optics; physics of light-matter interactions; and device design principles of LEDs, lasers, photodetectors, modulators, fiber and waveguide interconnects, optical filters, and photonic crystals. Device processing topics include crystal growth, substrate engineering, thin film deposition, etching and process integration for dielectric, silicon and compound semiconductor materials. The course also covers microphotonic integrated circuits and applications in telecom/datacom systems. Course assignments include three design projects that emphasize materials, devices and systems applications.

Potato Power

(Complete Item Description)

Abstract:: Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand the concepts of voltage, current and resistance.
