Abstract: The invention provides a selectively absorbing optical fiber that is transparent at pump wavelengths, and highly absorbing at signal wavelengths. The selectively absorbing optical fiber includes selectively absorbing species, such as rare earth ions, in concentrations sufficient to provide the desired absorbance selectivity. The fiber is useful as a fiber pigtail for pump lasers in optical amplifiers, where it can reduce the effects of multi-path interference by absorbing stray light with wavelengths in the signal band.

Abstract: The present invention includes a method of making a preform for an enhanced photosensitive fiber comprising depositing successive layers of optical material the inside a tube using modified chemical vapor deposition, and collapsing the layers of optical material in a reducing atmosphere with a reduced pressure (most preferably 0.2 to 0.4 torr). The present invention also includes a method of making an enhanced photosensitive fiber comprising making a preform using modified chemical vapor deposition wherein the preform is collapsed in a reducing atmosphere with a reduced pressure and drawing undertension (eg. 100 to 250g) the preform into a fiber. A grating can be formed by exposing the drawn fiber to ultraviolet light.

Abstract: The present invention provides devices including photosensitive bulk glass bodies (38), containing Bragg gratings (30). Preferably the bulk glass bodies (38) are batch meltable alkali boro-alumnio-silicate. The device comprises an input optical waveguide collimator(20) for collimating an input light beam (22) from an optical waveguide (24) to provide an unquided light beam (22) including wavelength range bands ( lambda R, lambda n); an internal bulk Bragg grating (26) including a transparent photosensitive bulk optical grating medium (28) with an internal modulated refractive index grating (30); at least one output coupler (32) for outputting at least one wavelength range band ( lambda R, lambda n); and a substrate structure for securing said bulk Bragg grating (26) relative to the input collimator (20) and the output coupler (32), the grating (26) disposed in the unguided light beam (22) wherein one wavelength range band ( lambda n) is transmitted through and one wavelenght range band ( lambda R) is reflected by the grating (26).

Abstract: An optically active waveguide laser 30 includes a multimode portion 126 for carrying more than one spatial mode at a predetermined wavelength chosen from a bandwidth including a pump wavelength 64 and the lasing wavelength 66. The multimode portion 126 has a first refractive index. A cladding portion 386 is proximate the multimode portion 126. A multimode grating 60, 56, or 62 is written on at least one section 26 of the multimode portion for reflecting the predetermined wavelength.
