Solving for mode propagation in step-index fibers.
One of the most persistent "problems" in optics is the . Traditionally, optical microscopes cannot resolve features smaller than half the wavelength of the light used. This physical constraint limits our ability to view biological processes at the molecular level or to manufacture smaller electronic components. Furthermore, as we try to shrink optical devices to fit on computer chips ( integrated photonics ), light tends to leak out of traditional waveguides when they are bent too sharply, leading to signal loss. The Solution: Metamaterials and Nanophotonics
