Optical demultiplexing characteristics are studied using a multielectrode distributed feedback laser amplifier. The gain maximum frequency is tunable over 20.6 GHz with a constant insertion gain (9.7 +- 1.2 dB) and a constant gain bandwidth (2.9 GHz), without any mode jump, by changing the driving current of the divided two electrodes. A single optical signal can be selected from two optical inputs separated by 15.4 GHz with an extinction ratio of better than -20 dB.
