OSE6421 Integrated Photonics

Course Goals

The course complements the OSE courses on ‘fundamentals of optoelectronic devices’, ‘computational photonics’ and ‘optical communication systems’ to deepen students’ education in photonic engineering.  The course’s goal is elucidating the key principles underlying the analysis and design of integrated photonic devices and circuits, with an emphasis on the engineering and practical aspects of them.  The students should be able to understand and design integrated photonic devices and circuits at the end of the course.  The course also introduces selected advanced research topics currently pursued in the field.

Course Approach

In order to analyze and design integrated photonic devices and circuits, it is necessary to study the components that constitute it, the principles that underlie their operation, and their functional characteristics from the perspective of a device engineer. To this extent, the course will begin with very briefly reviewing optoelectronic device principles as well as optical waveguide design. It will then quickly get into discussions on advanced integrated devices and circuits such as optical switches, optical transceivers, wavelength converters, arrayed waveguide gratings, etc.  The course will end with more state-of-the-art topics such as silicon photonics.

Prerequisite

• OSE 6111 Optical Wave Propagation
