摘要

This final report discusses development of Acousto Optic Tunable Filter (AOTF)technology for wavelength division multiplexing (WDM) in optical networks. The ability of tho AOTF to function as a digital or analog wavelength selective filter. with independent control of each wavelength channel or spectral window allows the AOTF to solve the seemingly unrelated problems of gain equalization and wavelength channel routing simultaneously. An AOTF with intrinsic gain als provides the capability for a lossless switch. Specific results of the effort include: packaged sidelobe suppressed AOTF's as hybrid polarization independent switches for gain equalization experiments requirements for passive and active filters for effective gain equalization in single and cascaded Erbium Doped Fiber Optic Amplifiers. single amplifier cascades delivery of a gain equalizer subsystem to ONTC, the development of a mathematical model for AOTFs with gain fabrication of waveguides in Er:Ti:LiNbO3, requirements for optimum pump and device packaging of AOTFs with gain. demonstration of the gain and noise properties of AOTFs with gain and determination of optimal system performance of an AOTF with gain.
