Abstract

We demonstrate real-time adaptive amplitude feedback in an AOM-based ultrafast optical pulse shaping system operating at /spl lambda/=1550 nm wavelength for optical communication applications. At the optimized feedback depth, a simple negative feedback algorithm converges in fewer than 10 iterations to within 5% of the target shape. This technique may be very useful for many applications including spectrum-sliced WDM.
