Department of Applied Physics

The Department came into existence as Faculty of Applied Physics in 1952 and was renamed as Department of  Applied Physics in 1979. The Department offers three M. Tech. courses namely,  Laser & Electro-Optics, Sensors Technology and Optical Communication & Photonics. We aim to train students for their career in academia as well as in industry in the frontier areas of Science & Technology. All our M. Tech. Programmes are balance of courses in fundamental science and technology helping students to  pursue career opportunities in Academics, Research & Industry as per their interest.

Ph.D. Programmme

The department of Applied Physics offers Ph.D. program in various research fields and will be advertised time-to-time on the website. We will admit students by national fellowships like CSIR,UGC-JRF or other equivalent national level exams and also through various means like institutional fellowship for GATE and NET qualified students. We also cater MoD sponsored candidates. Ph.D. students who joined department will undergo course work for first six months and followed by a comprehensive exam at end of his first year. Clearing this confirms his registration for Ph.D. program and he will continue to carry his research work in his respective field. After a satisfactory periodical reviews he/she will propose his work for thesis submission which will be evaluated by a panel of examiners. Finally, after successful completion of his an open defence he will be awarded a Ph.D. degree.


The department of Applied Physics offers Masters of Technology (M. Tech.) in three branch. The M. Tech. programme is of four-semester duration. In each of the first two semesters there are five courses and practical. There will be three continuous evaluation examinations and a final semester examination for every course. Half-yearly evaluation of the project takes place at the end of the third semester. At the end of the final semester the student submits a thesis and makes a presentation about the project, which is evaluated by the Internal and External examiners. Course syllabus has been updated periodically to keep pace with the contemporary technological advancement.

M. Tech. Programme
M. Tech. in Sensor Technology

Sensors is one area of science and technology which has witnessed a paradigm shift from conventional bulky components to extremely miniaturized and  smart  devices. The technological advancements in the area of Electronics, Electrical Engineering, along with the advancements in basic sciences in the areas of microfluidics, nanotechnology, biotechnology and photonics have been responsible for this concomitant growth in the development of current sensors. An interdisciplinary approach which will involve materials engineering, electronics and electrical engineering along with a flavour of chemical engineering and bio- engineering, is now required to understand such sensors. The objective is to make them faster, smaller, smarter and selective. This domain has, hence, seen large number of Industries, Institutes and small entrepreneur companies coming up in recent times. The programme intends to educate and train bright fresh students in the field of sensor technology to carry out challenging responsibilities in their future career, and meet the current challenges and foster the opportunities which the globe has to offer. This is an interdisciplinary course concerning broadly Electronics, Instrumentation, Sensors, Optics, Electromagnetism, Nanotechnology and Advanced Materials.

One of the greatest scientific discoveries of the twentieth century that has led to technological advancement touching all aspects of human life is the LASER. Applications of lasers range from medical applications, communications, and industrial applications to military applications. An understanding of laser technology is essential for an engineer working in many of the present-day cutting-edge technologies. The aim of this program is to train the students in the field of lasers, fiber optics, electro-optics, and photonics that would enable them to meet the challenges in this rapidly developing field.

M. Tech. in Optical Communication and Photonics

The rapid growth of networks and the internet over the past decade has been enabled by advances in photonics technology. Optical communication networks provide the high capacity ubiquitous connectivity that forms the backbone of global internet. Today, optics has become the way by which most of the information is communicated around the globe and is the only technology that is capable of meeting the exponentially growing demand for communicating information. The programme intends to impart training to selected candidates in the field of Optical Communication and Photonics that would enable them to meet the challenges in this rapidly developing field.
