Abstract

A novel structure, which converts wasted backward ASE to seed photons for the amplifying stage is suggested for a high power erbium doped fiber broadband source. Experimental results showed considerable increase in output power over 10dB for most radiation bands between 1540nm and 1620nm, with the simple addition of an unpumped EDF section in the conventional single pass structure, in addition to slight bandwidth extension.
