Abstract: A GRIN fiber lens has a silica-glass core whose refractive index has a radi al profile. The profile has a radial second derivative whose average magnitude in the core is less than about 1.7 x 10 -6 microns-2 times the value of the refractive index on the axis of the GRIN fiber lens.

Abstract: The performance of optical fiber Raman devices can be increased by substitution of a broadband reflector (typically a multilayer dielectric mirror) for some of the narrowband reflectors (typically fiber Bragg gratings) that are conventionally used to define the optical cavities of the device. The device exemplarily is a Raman laser or amplifier, and in preferred embodiments a broadband reflector reflects all the Stokesshifted wavelengths, such that the cavities are defined by the single broadband reflector and by a multiplicity of appropriately selected narrowband reflectors. Optionally the broadband reflector also serves to reflect the pump radiation.
