There are two options that you can pursue after an integrated M.Sc in photonics at CUSAT.

Industry Jobs - The jobs offered by the photonics industry of India are mostly sales. Yes, there are jobs in the telecommunications industry especially in the fiber optics sector which could fetch you some very good technical roles as well.

Research - Photonics is one of the very interesting topics to research upon. The field offers some very good opportunities in India as well as abroad. However, very few educational institutions in India have a photonics department and they also prefer physics students when they hire their professors. So getting a teaching job may also become difficult.

Anyway, if you are really interested in the subject then nothing should come between your choice because opportunities will appear over time.

Photonics is one of the high-tech subjects that is evolved hugely in the last 20 years. It has applications in the areas of communications, computing, medicine, industry, defense, and entertainment. Having my friends from CUSAT enables me to provide you some valuable insights into the course.

MSc Photonics in CUSAT is a good course to do. It is emerging fastly as mentioned before and has a huge potential. 

Integrated Course: One of the big advantages of choosing Photonics in CUSAT is that it is a 5-year integrated program compared to other institutes. This helps in dive deeper into the field of Photonics. 

Interesting Electives: Another highlight of the program is the choice of electives they provide with the course. 

Research Orientation: Students are subjected to a research atmosphere right from the start through the mini projects in the first and second semesters. 

Good for Competitive Exams: The course is more inclined towards photonics and includes some important and interesting subjects like nuclear physics, etc. Having exposure to these subjects will help a lot while preparing for competitive exams.

Course Fee & Faculties: The college has excellent facilities and experienced faculty to guide you. The course fee is also quite reasonable.

Placements: When it comes to placements even though there are no direct campus placements many students are placed in many top companies like Varroc, HELLA, Valeo, Tech Mahindra, etc. Apart from the placements, many students opt for Ph.D. programs in many abroad institutes.
