Prof. Ya Yan Lu is interested in computational photonics. More specifically, he has worked on numerical methods for optical waveguides, photonic crystals, diffraction gratings and nonlinear optics. optical waveguides (such as optical fibres) are structures that guide the propagation of light. Photonic crystals are periodic structures that can block light in certain frequency intervals. diffraction gratings are periodic structures on interfaces that have useful reflection properties. These structures are important in applications such as future integrated circuits based on light waves. Efficient numerical methods are important to engineers who design these structures for practical applications.
