Course objectives and basic requirements:
The course ‘Advanced Photonics – Theory and Applications’ has been developed for the 4th year undergraduate students of ZJU. The genesis of the said course is based on (a) the experience acquired through the teaching of advanced level photonics courses such as Optical Electronics, Optical Communication Systems and Semiconductor Photonics taught by the instructor Prof. Rajesh Kumar to senior undergraduate and masters students in IIT Roorkee, and (b) the research expertise of Prof Kumar in the area of photonics.
Course introduction:
Photonics is a key enabling technology for the modern devices and systems ranging from hand held gadgets to data centers that might be situated at far away locations for the users. In order to appreciate the photonics at deeper level, advanced level of theory of photonics and its applications need to be covered in a right proportion. The main contents are listed as follows: interaction of radiation with the matter/atomic system; the basic principle of the optical resonator and its application on frequency comb lines; the theory of laser oscillations; III-V microcavity lasers, and III-V-on-Silicon microcavity lasers fabrication and their characteristics; the amplitude, phase or frequency manipulation of the optical beam and its applications.

Test and Grading Criteria:
Evaluation will be done for total of 100 marks. Home work will be given by the instructor to the students as the teaching progresses. Home work will be designed to test (a) the conceptual knowledge (b) ability to derive certain important expressions and (c) skills for plotting the selected curves which are linked to concept building. Homework will earn a maximum of 20 marks.
Problem sheets will be given and solutions submitted by the student will earn maximum of 30 marks. Review of recently published selected research paper(s) by each student will earn maximum of 20 marks. At the end of the course, final written examination will be conducted and will account for 30 marks.
