Patent ID: 8755112

Claim:
A device for amplifying a plurality of optical signals comprising: a set of optical splitters arranged in a binary tree configuration including a root and leaves for receiving an initial optical beam from a pump laser coupled at the root of the binary tree configuration, where the leaves of the binary tree configuration provides a plurality of optical beams; and a multi-core fiber providing the plurality of optical signals; a plurality of fiber optical amplifying path (FOAP) circuits each configured to receive and amplify one of the plurality of optical signals, where each of the optical splitters at the leaves of the binary tree provides, to one of the plurality of FOAP circuits, one of the plurality of optical beams having a power required to amplify one of the plurality of optical signals; where each optical splitter in the binary tree configuration is selected based on its splitting ratio so that the optical splitters at leaves of the binary tree configuration provide the plurality of FOAPs with the plurality of optical beams each having the power required to amplify respective ones of the plurality of optical signals.
