    • A signal processing system processes an input signal in real time. The system includes a light valve array for selectively attenuating light incident thereupon in response to electronic control signals, a light source for providing illumination, a light-sensitive array for producing electronic output signals representing a processed version of the input signal in response to light incident thereupon, and control circuitry for generating and applying electronic control signals to the light valve array in response to the input signal. The electronic control signals are generated from the input signal and are adapted for implementing an arbitrarily-selected signal processing operation. The light valve array is situated between the light source and the light-sensitive array, such that the light source is selectively attenuated by the light valve array, and such that the selectively attenuated light is incident upon the light-sensitive array.

    • The present invention relates to an apparatus and method of making a Dense Wavelength-Division Multiplexer (DWDM) using a Fused-Biconical Taper ("FBT") technique. The DWDM according to the present invention comprises a multiple of Multi-window Wavelength-Division Multiplexers ("MWDMs") which cascade together in several stages, each stage has several MWDMs having an identical window spacing. For a N-channel DWDM, there are 2.sup.m-1 MWDMs cascaded in m-th stage, and the window spacing of the m-th stage MWDMs is 2.sup.m-1 .DELTA..lambda., where m is from 1 to (logN/log2), for example, the first stage (m=1) having 1 MWDM and the window spacing is .DELTA..lambda., the second stage (m=2) having 2 MWDMs and the window spacing is 2 .DELTA..lambda., the third stage(m=3) having 4 MWDMs and the window spacing is 4.DELTA..lambda., etc., and the (logN/log2)-th stage has (N/2) MWDMs with a window spacing (N/2).DELTA..lambda.. The number N could be 2, 4, 8, 16 or more.
