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....

  • Once you enroll for a Certificate, you’ll have access to all videos, quizzes, and programming assignments (if applicable). Peer review assignments can only be submitted and reviewed once your session has begun. If you choose to explore the course without purchasing, you may not be able to access certain assignments.

  • When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
