Abstract

Recent progress on an erbium-doped optical fiber amplifier (EDFA) pumped with a 0.98 micron laser diode is reported. An erbium-doped fiber with a very high gain coefficient of 11.0 dB/mW has been achieved using an extended VAD method. A high power 0.98 micron laser diode with a strained-layer InGaAs quantum well laser structure has been developed as the pumping light source. By employing these key components in the EDFA, a compact and highly efficient EDFA module has been fabricated successfully. The module size is only 36 cc. It attained a 33 dB net gain at 1.536 microns and it consumed only 175 mW of electricity.
