Abstract
An optical pump device including a pump source optically connected to an optical divider including one input channel and n output channels. The input channel is configured to receive a pump wave derived from the source and the n output channels are configured to output n pump waves, where n is an integer greater than 1. The pump device can be used in an optical amplification device. The device has applications in all domains in which several optical pumps are necessary, and more particularly in the domain of optical telecommunications, and for example for optical amplifiers.
