The accessibility and prevalence of modern communications can often obscure the complexity and sophistication of the underlying network that enables it. A constantly expanding network infrastructure supports the ever-increasing demand for faster and more reliable communications, higher-quality streaming, and greater bandwidth. In developed economies, most daily activities involve sending and receiving information across the globe with complete confidence in its safety. This confidence is reinforced by security measures such as secure HTTP labels, double-factor authentication, strong password recommendations, and a range of symmetric and asymmetric cryptographic transformations. These security protocols are updated regularly at almost every layer of the communication stack, except for the physical layer. Unfortunately, security measures at the lowest level of the communication stack, where data flows as electromagnetic fluctuations, are uncommon, particularly in fiber optics networks. Although implementing new layers of encryption in the physical domain would enhance security, it would also increase processing time and reduce data rates, which is not a practical solution given the exponential growth in data-sharing demands. Finding new approaches to implementing security measures in the optical, physical layer is necessary.Integrated photonics is pivotal in modern optical communication transmitters and receivers. It offers high efficiency and compact size, enabling the development of complex optical circuits in small form factors. Scalability allows for large systems to perform multiple tasks simultaneously. Silicon photonics integrated circuits, in particular, can offer the additional advantage of being integrated with electronics as hybrid Electronic Photonic Integrated Circuits (EPIC). However, their inherent cyber vulnerabilities increase as integrated photonics become more prevalent. Given their crucial role in advancing next-generation communication platforms, it is imperative to assess their security aspects and leverage this very technology to develop new innovative optical security features.In this dissertation, the complexities of information security in integrated optical systems are explored, and new foundational elements are proposed to enable the next generation of optical security while preserving channel capacities. The research introduces plasmonics-enhanced integrated optical devices capable of serving as unclonable functions, a critical component for tasks like authentication. Furthermore, the study investigates how various properties of light can be manipulated to perform operations analog to digital gates, an essential requirement for implementing stream ciphers. Specifically, polarization and mode encoding are examined in this context. Finally, adjoint-based inverse design is used for creating optimal integrated optical devices and circuits that can operate as optical gates at high speeds and are compatible with future optical physical layer encryption applications.
