Dispersion Trimming in a Reconfigurable Wavelength Selective Switch
... The active element in our wavelength selective switch (see Fig. 1, [6] and [7]) is a 2-D array of LCOS pixels. Light is sent from a fiber array through polarization diversity optics, which physically separate and align orthogonal polarization states to the high efficiency s-polarization state of a d ...
