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…
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…
Highly Oriented PZT Platform for Polarization-Independent Photonic Integrated Circuit and Enhanced Efficiency Electro-Optic Modulation
Suraj, Shankar Kumar Selvaraja
We demonstrate, for the first time, sputtered PZT as a platform for the development of Si-based photonic devices such as rings, MZI, and electro-optic modulators. We report the opt…
Polarization Independent Grating in GaN-on-Sapphire Photonic Integrated Circuit
Suraj, Shashwat Rathkanthiwar, Srinivasan Raghavan +1
In this work, we report the realization of a polarization-insensitive grating coupler, single-mode waveguide, and ring resonator in the GaN-on-Sapphire platform. We provide a detai…
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…
