We have proposed and demonstrated a high-power C+L-band erbium amplified spontaneous emission source using an optical circulator with double-pass and bi-directional configuration, which can provide a high output power of 177.8 mW with a ripple of 5 dB and a wide line width of 81.0 nm (1525.1-1606.1 nm) without adding any external spectra-flattening components. This designed configuration is also considered relaxing resonant lasing for averaged power stability with +/- 0.013 dB, allowing high pumping efficiency of 32.8%.
