Abstract
Disclosed is an L-band optical amplifier for amplifying optical signals with the wavelength band of the L-band. The L-band optical amplifier comprises an optical-amplifying section for emitting spontaneous emission and for amplifying the optical signals by pumping of the spontaneous emission, a mirror for reflecting the optical signals amplified by the optical-amplifying section to re-enter back to the optical-amplifying section, and a feedback loop connected with both terminals of the optical-amplifying section for causing spontaneous emission emitted from the optical-amplifying section to be fed back to the optical-amplifying section.
