Abstract
An amplifier operable with an electrical drive signal can amplify signal light having a signal wavelength. A laser diode has an active section with input and output facets. An optical isolator is integrated with a package that includes the laser diode. The active section is configured to generate pump light in response to injection of the electrical drive signal into the active section. The pump light has a pump wavelength different from the signal wavelength. A doped fiber doped with an active dopant is in optical communication with the signal light and is in optical communication with at least a portion of the pump light from the laser diode. The pump wavelength of the pump light is configured to interact with the active dopant of the fiber and thereby amplify the signal light.
