 Nonlinear optics, which governs the interaction of light with various media, offers a whole raft of useful applications in photonics, including multi-photon microscopy and multi-photon lithography. It also provides the physicists and engineers with a remarkable range of opportunities for generating light with interesting, novel, and potentially useful properties. As a particular example, entangled-photon beams generated via spontaneous optical parametric down-conversion exhibit unique quantum-correlation features and coherence properties that are of interest in a number of contexts, including imaging. Photons are emitted in pairs in an entangled quantum state, forming twin beams. Such light has found use, for example, in quantum optical coherence tomography, a quantum imaging technique that permits an object to be examined in section. Quantum entanglement endows this approach with a remarkable property: it is insensitive to the even-order dispersion inherent in the object, thereby increasing the resolution and section depth that can be attained. We discuss the advantages and disadvantages of a number of techniques in multi-photon and entangled-photon imaging and lithography.


Since 1995, Professor Malvin Carl Teich has been teaching and pursuing his research interests at Boston University as a faculty member with joint appointments in the Departments of Electrical and Computer Engineering, Physics, Biomedical Engineering, and Cognitive and Neural Systems. He is a consultant to the government and private industry and has served as an expert in numerous patent conflict cases. Dr. Teich is most widely known for his work in photonics and quantum optics and for his studies of fractal stochastic processes and information transmission in biological systems. His current efforts in photonics are directed toward the characterization of noise in photon streams and photodetectors while his interests in quantum optics relate to the development of imaging systems that make use of entangled photons and to the relative merits of using nonclassical vs. classical light. His work in fractals is directed toward elucidating the statistical properties of sensory-system actionpotential patterns and the heartbeat sequences of patients with coronary disorders.
Dr. Teich is a Life Fellow of the Institute of Electrical and Electronics Engineers (IEEE) and a Fellow of the Optical Society of America (OSA), the American Physical Society, the American Association for the Advancement of Science, and the Acoustical Society of America. He has received numerous prestigious awards, and has authored or coauthored some 350 refereed journal articles/book chapters and some 550 conference presentations/lectures. Dr. Teich holds six patents. He is the coauthor of Fundamentals of Photonics, which has been translated into four languages, and of Fractal-Based Point Processes. He has served editorial roles for several journals in photonics and quantum optics. He is a Traveling Lecturer of the OSA, and a Distinguished Lecturer of the IEEE Engineering in Medicine and Biology Society.
