Abstract
All-optical switching of an individual pulse within a sequence of amplified pulses is demonstrated in a conjugated polymer optical amplifier. The switching was achieved using a control pulse resonant with the excited state absorption. An extinction ratio of ∼5.5dB was observed, while the intensities of the remaining pulses in the sequence, spaced at 50ps intervals, were unaffected. A pump-probe study was performed and showed full gain recovery within 2ps.This publication has 25 references indexed in Scilit:
