Figure 3. (a) Tunable laser based excitation-emission spectra, (b) the emission spectra of a short section of Bi Er co-doped fiber when in-
creasing the 830nm pump power, (c) the increased emission between different pump powers, and (d) the relationship between the pump
power and the emissions at different wavelengths.
3. Discussion and Conclusions
In conclusion, we report a fiber white light source from
1000 nm to 1570 nm based on the Bi/Er co-doped fiber
and a single 830 nm laser diode pump and discuss its
mechanism based on emission observation, which ex-
pects to have applications in the spectral measurements
of optical fiber devices and the optical fiber sensing.
