摘要
By modifying appropriately the edges of the micromirrors, the effect of diffraction on the passband, modify at least one of input and output ports, or to permit the attenuation due to rotation of the micromirror about the switching axis By the, by using the rotation of the micromirror about the two axes of the switching axis and attenuation axis or to obtain the desired attenuation level, size of the micro-mirror edge diffraction, which is transmitted to the output port or all or any by inserting an aperture (opening) in the device or outside the focal plane in order to reduce, can be reduced by filtering the appropriate angular frequency diffraction grating or used to isolate the multi-channel optical signal to configure the spectral beam. Peak binding may be obtained by dithering the micromirror about an axis tangent to constant damping curves using simultaneous rotation about the attenuation axis and the switching shaft.
