COMPARISON OF ASE SPECTRUMS OF SINGLE PASS AND DOUBLE PASS Er, Yb, Er-Yb DOPED FIBER AMPLIFIERS
In this study, the amplified spontaneous emission (ASE) spectra of Erbium (EDFA), Ytterbium (YDFA), and Erbium-Ytterbium (EYDFA) doped optical amplifiers were obtained in single-pass and double-pass simulation setups, compared and interpreted with each other. The and spectra of the single-pass and d...

| Summary: | In this study, the amplified spontaneous emission (ASE) spectra of Erbium (EDFA), Ytterbium (YDFA), and Erbium-Ytterbium (EYDFA) doped optical amplifiers were obtained in single-pass and double-pass simulation setups, compared and interpreted with each other. The and spectra of the single-pass and double-pass setups of EDFA, YDFA, and EYDFA were compared using the ASE equations obtained at the Erbium energy level. The values applied in the single-pass and double-pass simulations, pump wavelength, pump power, amplifier length, and amplifier parameters, were assumed equally in both models. The pump wavelength for EDFA was 1480 nm, and the pump power was 1400 mW; the pump wavelength for YDFA was 960 nm, and the pump power was 800 mW, and these values were applied as 1025 nm and 1600 mW for EYDFA, respectively. The graphs at the output of the dual port spectrum analyzer showed that higher ASE values were obtained in the double-pass environment compared to the single-pass environment. |
