| 主权项 | 1. An arrayed optical amplifier comprising: at least one first amplifier including a first excitation light source controlled to a first temperature; at least one second amplifier including a second excitation light source controlled to a second temperature different from the first temperature; a control circuit coupled to the at least one first amplifier and the at least one second amplifiers; a first temperature control element, disposed in the at least one first amplifier, configured to control an operating temperature of the first excitation light source; and a second temperature control element, disposed in the at least one second amplifier, configured to control an operating temperature of the second excitation light source. | ||
