Abstract
A broadband partial reflector is located downstream from an optical combiner device. The partial reflector reflects a portion of the combined light back through the combiner device and back into the respective optical pump sources. There are no fiber gratings or other filters between the sources and the combiner device. Consequently, the sources are locked and/or stabilized according to the acceptance bandpass characteristics of the input ports of the combiner device. Since no gratings or other filters need to be located between the sources and the combiner device, the problem of insertion power loss due to spectral mismatch at the input ports can be avoided. In other words, self-aligned wavelength feedback stabilization is accomplished by reflecting a portion of the combined light signal back through the input ports of the combiner device.
