COMPENSATED BROADBAND FIBER LIGHT SOURCE WITH STABLE MEAN WAVELENGTH |
摘要 |
A fiber light source comprises a laser pump configured to generate a pump laser beam at a predetermined wavelength; a first segment of rare earth doped fiber; a second segment of rare earth doped fiber; and an optical coupler coupled to a first end of the first segment and a first end of the second segment. The optical coupler is configured to split the pump laser beam based on a power coupling ratio. The first segment generates a first stimulated emission having a first mean wavelength sensitivity to pump laser power fluctuations and the second segment generates a second stimulated emission having a second mean wavelength sensitivity to pump laser power fluctuations such that a combined stimulated emission is approximately insensitive to pump laser power fluctuations. |

1. A fiber light source comprising:
a pump laser configured to generate a pump laser beam at a predetermined wavelength; a first segment of rare earth doped fiber; a second segment of rare earth doped fiber; and an optical coupler coupled to a first end of the first segment and a first end of the second segment, the optical coupler configured to split the pump laser beam based on a power coupling ratio such that a first portion of the pump laser beam is coupled to the first segment at a first power level and a second portion of the pump laser beam is coupled to the second segment at a second power level; wherein the first segment of rare earth doped fiber generates a first stimulated emission having a first mean wavelength sensitivity to pump laser power fluctuations and the second segment of rare earth doped fiber generates a second stimulated emission having a second mean wavelength sensitivity to pump laser power fluctuations such that, when the first stimulated emission is combined with the second stimulated emission, a combined stimulated emission is approximately insensitive to pump laser power fluctuations. |
