CET317 Concepts of Nonlinear Optics

Course Provider

School of Physical and Mathematical Sciences (SPMS)



Academic Unit



This course aims to provide a good fundamental understanding of nonlinear optical phenomena, which are the working principles of major photonic devices and systems.

This course is part of:
- Graduate Certificate in Precision Instrumentation
- FlexiMasters in Precision Instrumentation

On completion of the course, the learners will acquire a good understanding of the physics and operation of optical device and systems that commonly available in advanced manufacturing as product or characterisation tools.


1. Nonlinear optical susceptibilities: linear & nonlinear optical susceptibilities, with a focus on propagation and coupling equations in linear and nonlinear media.

2. Second-order nonlinear optical effects: second harmonic generation and phase matching technology; sum- and difference-frequency generation; parametric amplification and oscillation; quasi-phase matching technique and introduction to photonic crystals.

3. Third-order nonlinear optical effects: four wave interaction and coupling equation; four-wave-mixing and phase conjugation; intense beam induced refractive index change, e.g. optical Kerr effect, self-focusing/defocusing, self-phase modulation; nonlinear optical absorption, e.g. two-photon absorption, saturable absorption and reverse saturable absorption; electro-optic, acousto-optics and photorefractive effects.


Participants with physical sciences or engineering background, or working engineer who wish to advance in their careers.
