Vadivu completed her bachelors in Electrical and Electronics Engineering from Mepco Schlenk Engineering College, Sivakasi in the year 2011 and graduated with masters degree in VLSI Design from SSN College of Engineering, Chennai in the year 2014. As a part of her master’s thesis, she worked on the design of Junctionless Tunnel Field Effect Transistors(J-TFET). In August 2014, Vadivu joined Photonics Research Lab as a Ph.D. student. Her field of research includes electro-optic modulators, high mobility low dimensional materials and complex oxide photonics, nanofabrication and integrated high speed photonic circuits. Vadivu enjoys drawing cartoons, doodle art and her other hobbies are reading short stories and watching movies.

Research:

Optical modulator is an active device that imprints an electronic signal onto an optical signal and it is one of the main challenging building blocks in silicon photonics to achieve high-performance data links. In this research, we aim at realizing an electro-optic modulators operating at 10 GHz or more. We plan to develop a plasma dispersion based electro-optic modulator in silicon platform using diffusion doping. To overcome the speed limitation posed by silicon platform, we also explore high mobility low dimensional materials and complex oxides like Vanadium dioxide, Barium Titanate on silicon platform to increase the modulation limits.
