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....
