She became part of a young and dynamic Photonics group working on various topics in the field. She and her students work mainly in three areas, viz., design, development and fabrication of novel diffractive optical elements, fiber based interferometry and optical MEMS. The branch of optics include the study of the properties of light on interaction with an 'element' as well as the constructi… text/html 2019-01-02T11:23:48+0530 Anonymous (anonymous@undisclosed.example.com) https://ee.iitm.ac.in/optics/doku.php?id=photonics_backup1:research:communications&rev=1546408428&do=diff Photonics at IIT Madras Home Academics Research People Publications Contact us Communication Optical communication is the backbone of our internet and mobile phones.
