Overview:

The course will provide a thorough coverage of physical optics, starting from Maxwell's equations. Real world applications or current state of the art practices will be used as examples and explored in the homework. After a short introduction, which stresses the E&M basis and prepares for later discussions of multilayer thin film interference, crystal optics and nonlinear optics, we will develop the theory of a general ray tracing algorithm similar to that used in commercial products. Its simplification will result in the matrix methods of paraxial optics and optical instruments. A discussion of apertures, stops, vignetting, and aberrations will supplement our optical instruments examples with design and performance issues. Real crystals are asymmetric. This has significant implications to light propagation. The fundamental physics will be explored to elucidate the observations. A study of several common two-beam interferometers and their applications will follow. Multiple beam interference will lead to the Fabry Perot interferometer and thin film interference. A rigorous treatment of thin film multilayers with examples for anti-reflection coatings, wavelength selective mirrors, and color separation should be expected. Limitations to their use will be given. Diffraction will be studied as a method to calculate the field from a known source. Several approximation schemes will be used, including that which leads to Fourier optics. A laser cavity example will yield the Gaussian beam and its propagation properties. We will then study Gaussian optics and the other aspects of lasers. Other topics include scattering, spectroscopy, remote sensing, holography and be reviewed before we delve into nonlinear optics. Second harmonic generation and other nonlinear techniques as time permits. Depending upon the interests of the particular class, the amount of time spent in each area can be altered or other topics covered (let me know).
