Abstract
An optical amplifier that is configured to amplify multiple optical signals using time-multiplexed optical energy pulses. The time-multiplexed optical energy pulses are supplied to multiple gain blocks of the optical amplifier in an alternating manner and each of the gain blocks uses the optical energy pulses that it receives to amplify one of the multiple optical signals. An optical amplifier may be configured with an optical switch to perform a switching function to direct the time-multiplexed optical energy pulses received from the pump laser to the gain blocks in an alternating manner. The total optical energy contained in each optical energy pulse may be independently controlled by varying its duty cycle or amplitude.
