Efficient Constructions of Streaming Codes
Streaming codes are a class of erasure codes that operate on a stream of packets and enable recovery of dropped or erased packets under a decoding-delay constraint. The primary focus of this thesis is on providing constructions ...
Capacity Computation and Coding for Input-Constrained Channels
The setting of the transmission of information over noisy, binary-input, memoryless channels is today well-understood, owing to the work of several information theorists, beginning with Claude Shannon. It is known that it ...
Coding Schemes for Secure and Reliable DNA-Based Data Storage
In DNA-based data storage, the desired information is encoded into the quaternary
sequence of synthetic DNA molecules, called oligos. We look at secure communication
via information-containing oligos in the usual three-party ...
Opacity and its Trade-offs with Security in Linear Dynamical Systems
Opacity is notion of privacy that is well-studied in computer science and discrete-event systems. In our work, we extend the opacity notion to linear dynamical systems. Opacity describes an eavesdropper’s inability to ...
Tailoring Van – der – Waal materials for nonlinear nanophotonics
Van der Waals or two-dimensional (2D) material are emerging nanomaterials which has shown tremendous potential in building next-generation nonlinear optical devices. Monolayer and multilayer 2D materials exhibit strong ...
Resonant Metasurfaces for Mid-Infrared Photonics
The field of photonics offers a robust platform for efficient light-based technologies,
directly impacting or serving as competent alternatives to address scientific problems. With the
advent and advancement of micro-nano ...
Index Coding over Noisy Channels and Some Applications
A broadcast channel that is very effective for disseminating common content becomes highly inefficient when the users request different content. To address this inefficiency of the broadcast channel over which a server ...
High Dimensional Quantum Information Technology Using Photonics: Protocol Development and Implementation Schemes
This thesis explores the realm of high-dimensional quantum information processing through the lens of photonics, focusing on developing and implementing quantum technologies based on d-level quantum systems known as qudits. ...
Excitonic complexes in semiconducting monolayers and their twisted heterojunctions
Monolayers of transition metal dichalcogenides (TMDCs) host excitons, a bound state of
electron and hole. Excitonic many-body complexes dominate the optical spectra obtained
from this system and manipulating these complexes ...
Adaptive Wideband Microwave Signal Processing Using Reconfigurable Integrated Photonics
The advancement of wireless communications in domains such as satellites, radars, 5G, and future technologies necessitates the utilization of broadband microwave and millimeter wave signal processing. Unlike their electronic ...
