摘要： It is found that the use of a multimode interference (MMI) section to flatten the pass-bands of an arrayed waveguide grating (AWG) multiplexer/demultiplexer or comb filter introduces undesirable non-linear wavelength dispersion into those pass-bands if that MMI section mixes modes of more than two different orders. This dispersion can be substantially compensated by the use of a tandem arrangement of two AWGs with MMIs of differing length chosen to provide complementary dispersions. In the case of a comb filter, an equivalent compensation can be achieved by arranging for the light to make a second passage through the AWG in the reverse direction.

摘要： In a method of operating a liquid crystal device having a liquid crystal composition with smectic-A properties, a first waveform is applied to optically clear the device so that it is substantially transparent to visible light and a second waveform is applied to disorder the material of the liquid crystal composition to afford a strongly light-scattering state. The first waveform has a higher frequency than the second, waveform, and the method comprises applying a modified waveform to partially clear at least a portion of the device from the light-scattering state.
