ECE 4500 OPTICAL ENGINEERING ECE 4500 OPTICAL ENGINEERING POSSIBLE OPTICAL ENGINEERING DESIGN TOPICS Acousto-Optic Tunable Filters Fiber optic tunable filters are needed for telecommunications applications. H. S. Kim, S. H. Yun, I. K. Kwang, and B. Y. Kim, "All-fiber acousto-optic tunable notch filter with electronically controllable spectral profile," Opt. Lett., vol. 22, pp. 1476-1478, Oct. 1, 1997. Acousto-Optic Tunable Lasers Lasers that can be tuned and can be integrated are needed in many applications. K. Schafer, I. Baumann, W. Sohler, H. Suche, and S. Westenhofer, "Diode-pumped and packaged acousto-optically tunable Ti:Er:LiNbO(3) waveguide laser of wide tuning range," IEEE J. Quantum. Electron., vol. 33, pp. 1636-1641, Oct. 1997. Add-Drop Filters In wavelength division multiplexing systems, add-drop filters are essential for adding and deleting channels. J. Capmany, P. Munoz, and D. Pastor, "Optimum design and performance evaluation of an all-fiber add-drop multiplexer based on a grating coupler," IEEE J. Select. Topics Quantum Electron., vol. 5, pp. 1392-1399, Sept./Oct. 1999. All-Optical Switches Optical switches can be constructed that are activated by light. D. M. Marom and D. Mendlovic, "Compact all-optical bypass-exchange switch," Appl. Opt., vol. 35, pp. 248-253, Jan. 10, 1996. Analog-to-Digital Converters Analog-to-digital (A/D) conversion needs to be performed rapidly and accurately in many applications. file:///A|/EXTOPICS.htm (1 of 25)1/17/2008 5:15:36 PM

ECE 4500 OPTICAL ENGINEERING M. Johansson, B. Lofving, S. Hard, L. Thylen, M. Mokhtari, U. Westergren, and C. Pala, "Study of an ultrafast analog-to-digital conversion scheme based on diffractive optics," Appl. Opt., vol. 39, pp. 2881-2887, June 10, 2000. Arrayed-Waveguide Grating Routers In telecommunications it is necessary to be able to switch and to rout various wavelength signals from one channel to another, such as with an arrayed- waveguide grating router. A. Sugita, A. Kaneko, K. Okamoto, M. Itoh, A. Himeno, and Y. Ohmori, "Very low insertion loss arrayed-waveguide grating with vertically tapered waveguides," IEEE Photon. Technol. Lett., vol. 12, pp. 1180- 1182, Sept. 2000. Asymmetric Fabry-Perot Multiple Quantum Well Electroabsorption Modulators These semiconductor devices may be used as reflection modulators. P. Zouganeli, P. J. Stevens, D. Atkinson, and G. Parry, "Design trade-offs and evaluation of the performance attainable by GaAs-Al(0.3)Ga(0.7)As asymmetric Fabry-Perot modulators," IEEE J. Quantum Electron., vol. 31, pp. 927-943, May 1995. Atmospheric Measurement Systems Measurement of atmospheric wind may be important in determining climatic conditions. G. M. Fisher, T. L. Killeen, Q. Wu, J. M. Reeves, P. B. Hays, W. A. Gault, S. Brown, and G. G. Shepherd, "Polar cap mesophere wind observations: Comparisons
