Abstract: A pump laser package may include an input fiber to send signal light on a first optical path. A first lens may be arranged on the first optical path. The pump laser package may include a source to send pump light on a second optical path. A second lens and a negative lens may be arranged on the second optical path. The first lens and the negative lens may be arranged to create a virtual image associated with the pump light. The pump laser package may include an output fiber on a third optical path. The first lens may be arranged on the third optical path. The pump laser package may include a combiner to receive the signal light on the first optical path, receive the pump light on the second optical path, and send the signal light and the pump light on the third optical path.

Abstract: A programmable multicast switch may include a first set of optical ports and a second set of optical ports. The programmable multicast switch may include a plurality of groups of optical devices optically connected in a cascading arrangement. At least one optical device in each of the plurality of groups may be a tunable optical device. Each group may be connected to an optical port of the first set of optical ports. The programmable multicast switch may include a plurality of controllers to tune each corresponding tunable optical devices. The programmable multicast switch may include a processor to control the plurality of controllers. The programmable multicast switch may include a plurality of optical switches connected to each of the groups of optical devices. Each optical switch of the plurality of optical switches may be connected to an optical port of the second set of optical ports.
