Abstract： |
There is a sort of optical fibre parameter amplifier, and it attributes the optical fibre communication and the nonlinear optical fibre optics area. The usual optical fibre parameter amplifier adopts the coherent source laser to be the pump light, and its wavelength plus has the disadvantage that it changes acutely along with the change of the signal polarization state and the cost pump light is dearly and its request of the working condition is high. In order to resolve this problem the optical fibre parameter amplifier in this invention that its pump is offered by the unpolarized and incoherent lamp house not only has the advantage that the wavelength does not change along with the signal polarization state, but also its cost debases greatly. |
