Dr. Shanti Bhattacharya joined the Department of Electrical Engineering in the year 2005. At that time, her group worked mainly in the design, development, and fabrication of novel diffractive optical elements, fiber-based interferometry, and optical MEMS. Her areas of research have now expanded to include complex light generation and diffractive metasurface design and fabrication.

Combined MEMS actuator and grating

We report the design and fabrication process optimisation of an optical MEMS device, addressing the various processing difficulties experienced in the fabrication of silicon-on-insulator (SOI)-based devices

Transform-based phase retrieval techniques

We discuss the three different off-axis Optical Phase Retrieval algorithms, which are the Fourier transform, continous wavelet transform, and Hilbert transform methods

MetaOptics Software

We develop a open-source software using Python to create Metasurface GDSII layouts for a given phase function

DOE Simulator and GDSII Convertor

We developed an open-source software built in Python to perform scalar diffraction simulations and subsequently convert the Phase profiles into GDSII format for lithography
