There are to few phisical explanation all the course is about writting formulas over a board with many many few explanation of its phisical meaning. I had a subject in my degree that covers about the 80% of the course and anyway I get lost in the videos coping formulas.

This course is limited to just copying and pasting equations without going deep into both the physical fundamentals and the importance of the things being studied, to fully understand the concepts, several previous courses are required

Course provided good material and challenging concepts which is what I was looking for. However, a lack of examples in solving problems made it more difficult to solve a number of problems than it should have been. I would recommend the course for someone who at least has a decent background in the material and is interested in it. If not, it might be challenging to follow.

The course is completely theoretical, it would be nice to have a more hands-on topics.

You need to take another course to pass the exams because either the questions are not clear or haven't been mentioned in the lessons. Some hints are given in the discussion forums. But still, the course is not good.

Useful for me, with pretty good lectures (I really like a real lecture with writing on a board compared to just slides). It was nice to also see almost no mistakes in the quizes, which was very good for my sanity.

It will be great to re-evaluate the weekly quizzes and also will be great to have a course moderator. Thank you!

Discussion forum is truly helpful in completing the quizes!

Very good course about semiconductor lasers.

The content is very good but the way it is delivered could be improved.

A lot of new and complex concepts are introduced too quickly. I had to make my own research independantly to really understand the concepts.

This course is really informative. The assignments allow you to think over the course details critically and analytically. I enjoyed this course overall but the last two weeks were really tough as compared to the previous ones.

The lectures don't contain conceptual information needed to gain clarity to solve the given quizzes easily. Important concepts are informed about only through formula without enough explanations.

Interessting content but the support is very poor. Also the traffic in the forum is pretty low.

too many formules, without a background idea of what we are really learning
