Title：Advanced Photonics – Theory and Applications

Class Hours/Week:  3-1                  Credit: 2

Category：Specialty

Prerequisites：Basic Electromagnetic Theory, Basic Semiconductor Physics

Audience：Undergraduates

Teaching manner:

  1.  Teaching will be done in ONLINE mode using Microsoft Teams (https://www.microsoft.com/en-in/microsoft-teams/group-chat-software). If needed, any other alternatives such as ZOOM or WebEx may be used.

  2. Assignments will be given for each chapter once significant portion of a particular unit is covered.  

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.
