Abstract: (2796 Views)
In this paper, an optically-controllable continuous-wave single-mode double-clad ytterbium (Yb) doped silica based on the nonlinear electromagnetically induced transparency (EIT) is numerically modeled on a master-oscillator fiber power-amplifier (MOFPA).Here, the Si nanocrystals are embedded in SiO2 host over selected regions of the output coupler. By applying the external control pump field through a diode laser on the fiber Bragg grating (FBG) can be change the refractive index of the EIT material, which results in a change the percentage of the reflection of the output mirror (between zero and 100%), as well as the achievement of one Optical system is adjustable.
