The course objective is to familiarize students to the research frontiers in Nano and Quantum Optics. The course will discuss fundamental principles with emphasis on developing intuitive understanding and developing analytical techniques.This course is primarily designed for post-graduate and PhD research scholars in Photonics. Senior undergraduate students pursuing ECE/EE/Physics or related programs will also benefit by exposure to this frontier area of research. Faculty interesting in expanding their knowledge base and/or prepare for research programs will also find it beneficial.

Advantages and disadvantages
Advantages
Taught by IIT and IISc professors, and it follows the Indian university syllabus closely.
All videos and assignments are free on NPTEL and SWAYAM.
The certificate is recognised by many Indian universities for credit transfer and by GATE aspirants.
Great for GATE and semester exam preparation.
From Indian Institute of Technology Hyderabad, a well-regarded name.
Completely free.
Self-paced: start any time.
A clear syllabus (12 parts) you can see before you start.
Disadvantages
The certificate needs a proctored exam at a centre, which has a fee.
Recorded classroom lectures: thorough, but slower than made-for-online courses.
New runs start on fixed dates (January and July).
Learning is free, but the certificate costs money.
Some points apply to every course of this kind; see how we rank.
Free to learn
Free: Every video and assignment is free on NPTEL and SWAYAM. Enrol when the next run opens.
Certificate: Optional. It needs a proctored exam at a centre, which has a fee.
