Syllabus

WEEK 1
Semiconductor fundamentals
Light emitting diodes and semiconductor lasers is a really special course, and probably one of my favorite. In it, you will learn the fundamental operating principles, design, fabrication techniques and applications of two of the most widely used light emitting devices in the world today - light emitting diodes and semiconductor lasers. For module 1, I am really looking forward to introducing you to the magical world of semiconductors. In this module, we will review the basics of semiconductor physics and you will learn how we can manipulate the materials to tailor electrical and optical properties.

WEEK 2
Radiative recombination in semiconductors
In the last module, we learned about the basics of semiconductor physics. In this module, we will apply this knowledge to understand how semiconductors emit light, and the basis for optoelectronic devices such as lasers and light emitting diodes.

WEEK 3
Light Emitting Diode (LED)
In the last module, we learned about how semiconductors can emit light. In this module, we will apply this knowledge to learn about the basics of light emitting diodes. These devices are everywhere you turn and you now have the tools to develop a complete understanding of their operation.

WEEK 4
Fundamentals of semiconductor lasers
In the last module, we learned about light emitting diodes or LEDs. Now, we will use our knowledge of semiconductors and in particular, radiative recombination, to tackle an even more powerful device, the semiconductor laser. This technology is probably the most successful laser technology of our time, with every compact disc player incorporating a 6-cent semiconductor laser. I hope you enjoy this unit as much as I do.

WEEK 5
semiconductor laser design principles
In the last module, we learned about the basics of semiconductor lasers. Now, we will extend this knowledge to understand the design principles behind this very successful technology. After the module, you will wonder, as I do, how it is possible to produce a semiconductor laser for 6 cents!

WEEK 6
advanced semiconductor laser design principles
In the last module, we learned about basic design principles for semiconductor lasers. In this module, we will take this one step further and learn about advanced concepts that have enabled the current generation of semiconductor lasers. Stay tuned for the magic!

Course 2 begins with the definitions of resistivity and sheet resistance of semiconductors and metals and emphasizes the importance of working with the correct units for each. We see how to calculate the sheet resistance of a thin conducting film once we know its resistivity. A method to determine the contact resistance using the transfer length method is described, along with the definition of the specific contact resistivity. Current-voltage (IV) measurements of p-n junction diodes are used to extract key device parameters such as the ideality factor and series resistance.

Arduino senses the environment by receiving inputs from add-on devices such as sensors, and can control the world around it by adjusting lights, motors, and other actuators. In this class you will learn how and when to use the different types of sensors and how to connect them to the Arduino. Since the external world uses continuous or analog signals and the hardware is digital you will learn how these signals are converted back-and-forth and how this must be considered as you program your device. You'll also learn about the use of Arduino-specific shields and the shields software libraries to interface with the real world.
