Useful Books: R. W. Boyd, Nonlinear optics, academic press, 2003, K.K.Sharma, Optics, Principles and applications, Elsevier 2006
Lectures: 90% attendance policy, lectures varied between bad and poor, most of the course was on the blackboard with slides used occasionally.
Assignments/Tutorials: No tutorials or practice questions were provided. The course was on the difficult side with many many new ideas and a fairly fast pace. The grading can be seen on ASC.
Exams: Midsem, Endsem, Project (hand-written research proposal on topic from a list in teams of 3-4)
Online Study Material: The prof's course on Non-Linear Optics on NPTEL
Advanced Follow up Courses: Any of the optics courses.
Pro-tip: Overall quality was bad so we had to rely on self-study. The course content and instructors for the course have been changing a lot, so the course is extremely instructor dependant.
