>>> EURASIP Journal on Applied Signal Processing Special Issue on Signal Analysis Tools for Optical Information Processing The application of traditional signal analysis tools (e.g., Fourier transforms) to a wide variety of optical problems (e.g., diffraction, spatial filtering, holography, dispersion, etc.) has led to a new and deeper understanding of these optical problems. Novel analysis and synthesis methods for different photonics devices (e.g., fiber gratings, ring resonators, etc.) have also been developed based on well-known signal processing tools. The use of different photonic technologies for processing spatial or temporal information in the optical domain is also a field of growing importance, with a strong potential for interesting applications in fields such diverse as optical telecommunications, image processing, and optical computing, to name only a few. Advantages of processing the information in the optical domain include the tremendous available bandwidth and the parallelism intrinsic to the optical approach, which translate into ultrahigh processing speeds, which otherwise are not possible. This special issue is seeking original research contributions regarding (i) the application of signal analysis tools to optical problems and (ii) the proposal and demonstration of innovative technologies, devices, and architectures for all-optical information processing in the spatial or temporal domains. Topics of interest include (but are not limited to): o Fourier optics and image optical processing o Novel material, devices, and architectures for spatial and temporal optical signal processing o Fractional transforms for optical signal analysis o Phase-space analysis (e.g., Wigner-Ville analysis) of optical signals and fields o Joint time-frequency representations (e.g., Wavelet analysis) of optical signals o Ultrafast optical pulse processing and shaping o Optical filter design and analysis o Signal processing tools for the analysis and synthesis of photonic devices o Applications of optical signal processing for optical communications, optical computing, pattern recognition, etc. Authors should follow the EURASIP JASP manuscript format described at the journal site http://asp.hindawi.com/.
