Abstract: A fiber light source having, for instance, a 980 nm pump laser for pumping an erbium-doped optical fiber via a 980/1550 nm WDM coupler. The pumped fiber emits 1550 nm light. A portion of the 1550 nm light goes to a filter via the WDM coupler. The filter shapes the spectrum of the 1550 nm light. The filter is a passive device that may be made from erbium-doped fiber. From the filter the 1550 nm light goes through an isolator or a circulator on to an optical device for which the light is specially made. Such device may be an fiber optic gyroscope. By adding a narrowband optical fiber grating at the output of the pump laser to tune its output, the fiber light source is further improved in stability under variations of ambient temperature and light source drive current.

Abstract: An example of a fiber optic light source has a pump laser that feeds light to a length of doped optical fiber. The optical fiber produces light that has a mean wavelength, for example in the range of 1515 nm to 1544 nm, such that the light is substantially unaffected when exposed to weapons level radiation.

Abstract: An ultra-low RIN band fiber light source is provided. In one embodiment, the fiber light source includes at least one segment of optical fiber, one or more pump lasers, at least two wavelength division multiplexers and a reflective device. Each pump is adapted to output a power signal having a select wavelength and a select power level. Each wavelength division multiplexer is adapted to couple an associated power signal from at least one of the one or more pumps into the at least one segment of optical fiber to generate amplified spontaneous emission (ASE) signals having select parameters in the at least one segment of optical fiber. The reflective device is coupled to an end of the at least one segment of optical fiber and is adapted to reflect back a portion of the ASE signals.
