We present small-signal response measurements on all-optical switches based on a single SOA followed by an optical filter. Both asymmetric MZI and band-pass type filters are investigated and theoretical predictions of a large modulation bandwidth enhancing effect are verified. The small-signal measurements of the DISC switch (SOA and asymmetric MZI) are the first of their kind.
