Abstract
The transient crosstalk in a phase-only liquid crystal on silicon (LCOS) based wavelength selective
switch using a Fourier transform setup was investigated. Its origin was identified using an
in situ test procedure and found to be related to the transient phase
patterns displayed by the LCOS device during the switching. Two different methods were proposed to reduce the
transient crosstalk without the need to modify the optics or electronics in use. Experimental results show both
methods are able to reduce the worst-case transient crosstalk by at least 5 dB.
