- Abstract :
A simpler and more straightforward approach for the transfer response
measurements of a programmable bipolar optical transversal filter is
demonstrated by using the amplified spontaneous emission (ASE) noise
of an erbium-doped fiber amplifier. The ASE noise is used as the
source of optical quasewhite noise imput because of its broad
bandwidth, and the output is directly observed with an optical
spectrum analyzer and an autocorrelator. This technique is suitable
to evaluate the coherent type of optical filters.
