Alumni Interaction

We conducted a lecture series where our alumni shared their research work and experience to engage our
research students with various opportunities.

Erasmus Mundus Master: exploring European Culture, Universities and Large-Scale Facilities

Germany, February 10
MaMaSELF+ is a two-year international Master’s course in Materials Science fully taught
in English, delivering multiple master’s degrees, and recognized as a European
formation of excellence in this field since 2007. The consortium includes 6 primary
European Universities in the field of Materials sciences, Engineering Physics, and
Chemistry in France, Germany, Italy, and Poland. The joint program covers the
fundamentals of Materials: structure and dynamics of condensed matter, and chemical,
mechanical and physical properties of materials. One specific aim of the MaMaSELF
program is to emphasize the application of "Large scale facilities" for the characterization
and development of materials. The program structure consists of 3 semesters of lectures and a
4thsemester dedicated to a Master-thesis / internship in highly recognized European Universities.

Applications of Different Types of Optical waveguides

Dr. Ritapa Bhattacharjee, Post-Doctoral Fellow - City University of London, United Kingdom, China, April 18
Optical waveguides provide a non-destructive technique to find different types of testing
and detection application in several fields. The designing of optical waveguides plays a
key role to determine their operation. Some common optical waveguides are optical
fibers, rigid bulk waveguides, slot waveguides, etc. It is possible to regulate the effective
refractive index of light by changing the size, shape, and material of a particular
waveguide. Optical waveguides have various uses in dispersion engineering, harmonic
generation, ultrafast optics, etc. Here application of photonic quasi-crystal fibers for
second harmonic generation and the application of slot waveguides as the sensor will be mainly focused
on. Further, it will be shown how the geometry and material of a particular waveguide affect the effective
refractive index and power of light passing through the waveguide and thus affects the required applications.

Recent advances in plasmonic sensor-based fiber optic probes for biological sensors

Dr. Aruna Gandhi MS, Post-Doctoral Fellow - Peking University, China, June 23
Diagnostic tools have been the need of the hour
owing to the several threatful diseases in human
society. With the appreciable increase in the
incidences of risk factors, there is a great need for a
tool that can be quick and reliable with high accuracy
in detecting infected bioagents in biological
samples. The fiber-based biosensor can serve as a
low-cost, efficient device for day-to-day
applications. Fiber optic plasmonic sensors use an
optical field to measure biological agents. Due to their unique sensing performances, fiber optic plasmonic
sensors turn out to be potential alternatives to conventional fiber optic sensors. Fiber optic plasmonic
sensors use optical transduction mechanisms to enhance sensitivity and resolution. The transduction
