Paper Abstract

We present a novel co-axial dual core resonant leaky fiber (DCRLF) design for inherent gain equalization of S-band erbium doped fiber amplifier (EDFA). Spectral leakage loss variation of the structure has been utilized to suppress the amplified spontaneous emission (ASE) in the C-band and to achieve inherent gain flattening in the S-band of an EDFA. We show 19 dB flat gain with ± 1.1 dB ripple over 30 nm bandwidth (1490-1520 nm) and 20 dB flat gain with ± 2.1 dB ripple over 40 nm bandwidth (1485-1525 nm). We have also carried out a detailed tolerance study of the designed Sband EDFA with respect to the outer cladding parameters.
