Photonics (3 units). Fundamentals of fiber and waveguide optics and
applications to optical components and systems for fiber communication technology. Prerequisites: OPTI501,
OPTI505R, OPTI507, OPTI511R.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and information processing.This course is designed to be device oriented, with many practical examples of photonics components. The students will learn how the devices are made, designed and operated. The course can be broadly divided into two parts. The first part covers fundamentals such as theories of dispersion, absorption and birefringence. Thorough understanding of these concepts is required for the rest of the course. This review will be followed immediately by studies of passive components such as gratings, Fabry Perot filters and Bragg mirrors. We then move to wave propagation in planar geometries, specifically different kinds of integrated optics devices. There will be a midterm exam, which will provide students with enough feedback on their performance in order to drop the class if they are doing poorly. The second part of the class covers wave propagation in optical fiber with applications to optical networks, telecommunications, and optical interconnects. Different type of fiber-based devices are examined. We will study various types of fiber amplifers, specialty fiber and nonlinear effects in fibers that impact optical network performance. Many practical aspects of fiber-based devices will be covered including their design, fabrication and packaging; relevant reliability standards will also be introduced. Finally, we will examine different kinds of active lightwave devices including optical interconnects, LEDs, laser diodes and photodetectors; many of these devices will play a role in emerging data center and super computer architectures.
