Directional atomic layer etching of MgO-doped lithium niobate using Br-based plasma
Ivy I. Chen, Mariya Ezzy, Emily Hsue-Chi Shi +8
Lithium niobate (LiNbO, LN) is a nonlinear optical material of high interest for integrated photonics with applications ranging from optical communications to quantum informati…
Automated retinal vessel segmentation based on morphological preprocessing and 2D-Gabor wavelets
Kundan Kumar, Debashisa Samal, Suraj
Automated segmentation of vascular map in retinal images endeavors a potential benefit in diagnostic procedure of different ocular diseases. In this paper, we suggest a new unsuper…
3-D poling and drive mechanism for high-speed PZT-on-SOI Electro-Optic modulator using remote Pt buffered growth
Suraj, Shankar Kumar Selvaraja
In this work, we have demonstrated a novel method to increase the electro-optic interaction in an intensity modulator at the C-band by optimizing the growth methodology of PZT with…
DFT analysis and demonstration of enhanced clamped Electro-Optic tensor by strain engineering in PZT
Suraj, Shankar Kumar Selvaraja
We report 400\% enhancement in PZT Pockels coefficient on DFT simulation of lattice strain due to phonon mode softening.The simulation showed a relation between the rumpli…
Sputter-deposited PZT-on-Silicon Optimization for C-band Electro-Optic Modulation
Suraj, Shankar Kumar Selvaraja
Ferroelectric materials exhibit interesting electric, mechanical and optical properties. Particularly,tin-film lead zirconium titanate (PZT) has been used as a standard piezo-elect…
Rashba and Dresselhaus effects in doped methylammonium lead halide perovskite MAPbI
Megha Arya, Preeti Bhumla, Sajjan Sheoran +2
Inorganic-organic lead halide perovskites, particularly methylammonium lead halide (MAPbI) perovskite, is perceived to be a promising material for optoelectronics and spintroni…
