Students first explore how photons are produced through transitions between energy states, and how this connects to the broader electromagnetic description of light. From there, the program develops the theory of electromagnetic wave propagation — wavelength, frequency, phase, polarization, energy and the behaviour of light as it travels through different media.
Only then do we move into classical optics. What happens when light reaches a mirror, passes through a lens, encounters an interface, or travels through a narrow aperture? Students investigate reflection, refraction, image formation, diffraction, interference and polarization through hands-on experiments.
The next step is to understand how light is measured. Using photodiodes, cameras, optical sensors and polarizers, students can capture real optical signals and convert them into quantitative data. A laser beam, for example, can be imaged and analysed using MATLAB to determine beam profile, spot size, intensity distribution and divergence.
The program then enters the world of lasers. Students explore stimulated emission, population inversion, optical cavities, coherence and laser-beam formation, followed by experiments on wavelength, polarization, interference and coherence.
Finally, we move toward advanced photonics. Students see how controlled light enables spectroscopy, optical communication, LiDAR, imaging, semiconductor lithography and precision sensing, before looking at frontier applications such as high-intensity lasers for particle acceleration, laser-driven electron beams, laser-plasma interactions, terahertz generation, ultrafast science and emerging photonic technologies.
Photon → Electromagnetic Wave → Optics → Measurement → Laser → Photonics → Frontier Technology
By the end, students should see light not simply as something we observe, but as a physical system that can be generated, controlled, measured and engineered for extraordinary applications.
