COURSE OBJECTIVES: When a student completes this course, s/he should be able to:
• Have an understanding of photonic information processing.
• Know what is the difference between coherent and incoherent light.
• Understand how coherent light propagates in free space — that free-space propagation is equivalent to a linear shift-invariant filter.
• Understand the differences between plane waves and Gaussian beams of light, the latter being the outputs of most lasers.
• Do detailed calculations relating to the propagation and focusing of Gaussian beams of light.
• Know how free-space diffraction affects the design of satellite-to-satellite and other open-space optical communication links.
• Understand imaging with thin lenses and the origin of the fundamental resolution limit.
• Know how light propagates in anisotropic media and what are electro-optic and acousto-optic effects.
• Understand basic concepts of electro-optic and acousto-optic modulation of light.
• Know how the above concepts are used in photonic information processing.
• Apply the theory of light propagation to understand how holography and optical storage works.
• Be prepared to take advanced courses in the area of photonics.
