Purcell Enhancement of Spontaneous Emission of a Quantum Emitter on a Waveguide
Sushma Gali, Komal Sharma, Jaydeep Kumar Basu +1
We investigate the effect of a waveguide on an emitter spontaneous emission in its vicinity. The impact of various possible orientations of an emitter with respect to the waveguide…
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…
On-Chip Chemical Sensing Using Double-slot Silicon Waveguide
Sushma Gali, Akshay Keloth, Shankar Kumar Selvaraja
In this paper, we present refractive index measurement using a double-slot silicon waveguide-based Mach Zehnder interferometer. We present a double-slot waveguide that offers the b…
