Abstract

In this paper, we investigate simultaneous 853 nm + 1533 nm amplification, and wavelength conversion between 1533 nm and 853 nm in Er³⁺-doped fluoride fiber. Based on our simulation results, simultaneous 853 nm (⁴S_3/2→⁴I_13/2 transition) + 1533 nm (⁴I_13/2→⁴I_15/2 transition) amplification, and wavelength conversion between 1533 nm and 853 nm can be realized in Er³⁺-doped fluoride fibers with the excitation of a 974 nm laser diode, respectively. Furthermore, we investigate the interactions between 853 nm and 1533 nm amplifications, and discuss their effects on simultaneously 853 nm + 1533 nm amplifier. The crosstalk between 853 nm and 1533 nm signals is very weak because of relatively long lifetime (~10 ms) of the ⁴I_13/2 level. By introducing a cavity for 853 nm or 1533 nm lasing into the system, the possibility of wavelength conversion from 1533 nm to 853 nm or from 853 nm to 1533 nm in Er³⁺-doped fluoride fiber excited at 974 nm is clarified, which can be used as the wavelength converter or optical switch between public (the third window: ~1533 nm) and local (the first window: ~853 nm) networks in future networks.
