Integrated Photonics Devices and Circuits

Lightwave technology and photonics played an important role in the progress of long-haul fiber optic communication systems. Recent advances in CMOS compatible silicon photonics technology has made it feasible for on-chip high-speed optical interconnects, biomedical lab-on-chip sensors, microwave photonics system-on-chip, linear optical quantum computing (LOQC) and highest degree of secured quantum key distribution (QKD) photonics chips with large-scale integrated components. In this course, students will learn theory of integrated optical waveguides and working principles of various integrated photonics devices (passive and active). The design rules and technology for large-scale photonic integrated circuits will be also addressed in this course.INTENDED AUDIENCE : Engineering UG/PG Students and Research ScholarsPREREQUISITES : EM Fields/Engineering Electromagnetics, Fundamentals of Semiconductor DevicesINDUSTRIES SUPPORT : Semiconductor Industries
