Integrated Micro-Ring Photonics

Micro-ring resonators (MRRs) are employed to generate signals used for optical communication applications, where they can be integrated in a single system. These structures are ideal candidates for very large-scale integrated (VLSI) photonic circuits, since they provide a wide range of optical signal processing functions while being ultra-compact. Soliton pulses have sufficient stability for preservation of their shape and velocity. Technological progress in fields such as tunable narrow band laser systems, multiple transmission, and MRR systems constitute a base for the development of new transmission techniques. Controlling the speed of a light signal has many potential applications in fiber optic communication and quantum computing. The slow light effect has many important applications and is a key technology for all optical networks such as optical signal processing. Generation of slow light in MRRs is based on the nonlinear optical fibers. Slow light can be generated within the micro-ring devices, which will be able to be used with the mobile telephone. Therefore, the message can be kept encrypted via quantum cryptography. Thus perfect security in a mobile telephone network is plausible. This research study involves both numerical experiments and theoretical work based on MRRs for secured communication.

"The phenomenon of “slow light” has received considerable attention over the last few years. The term slow light refers to the propagation of an optical signal through a medium with a speed considerably less than speed of light in vacuum. Controlling the speed of light is important for many applications such as optical communication systems, optical buffering, data synchronization, optical memories etc. Recent research has established that the velocity of light pulses can be controlled through micro-ring resonators (MRRs). This book is basically a research-based study on MRR systems and their utilization and application in optical communications. [...]This book cannot be used as a textbook, but can be used as a reference for undergraduate and graduate researchers and for professional engineers with prior knowledge of applied optics and optical communication."Book review by Ishtiaque Ahmed, Member of OSA, IEEE, APS in "Optics and Photonics News", August 2017
