ABSTRACT:
Disclosed is an optical amplification device comprising a pulser for pulsing a multi-channel signal which has been wavelength division multiplexed; a pulse signal disperser for dispersing the pulsed signal at each wavelength and outputting a dispersed pulse signal; and an optoelectronic converter for converting the dispersed pulse signal to an electrical signal. The number of channels of a multi-channel signal can be counted by counting the number of peaks in a time waveform of the electrical signal. The pulse signal disperser can be realized by using a high dispersion medium having high wavelength dispersion. The pulser can be realized by using an optical switch utilizing a mechanical, acousto-optical or electro-optical effects. The optical signal channel counter can be applied in an optical amplification device and stable optical amplification can be performed by counting the number of channels of an inputted optical signal and outputting pump light in compliance with said number of channels. The number of channels of a multi-channel signal can thus be counted accurately and the configuration of the counter which executes counting can be simplified.
