Application 10/615,389
THE INVENTION
The Appellants claim an optical amplification module for collectively
amplifying signal light. Claim 3 is illustrative:
3. An optical amplification module for collectively
amplifying signal light having multiplexed a plurality of
channels in a single wavelength band including a wavelength
region having a wavelength of 1610 nm or longer, said optical
amplification module comprising:
a Bi oxide based optical waveguide, comprised of Bi
oxide based host glass, including an optical waveguide region
doped with Er element, for propagating the signal light;
a pumping light supply system for supplying the optical
waveguide region with pumping light so as to generate a
population inversion within the optical waveguide region of
said Bi oxide based optical waveguide; and
a control unit for adjusting an optical power of the
pumping light supplied from said pumping light supply system
to said Bi oxide based optical waveguide so as to yield a
relative gain non-uniformity of less than 25% in a net gain
spectrum of said Bi oxide based optical waveguide at a
predetermined operating temperature within an operating
temperature range of said optical amplification module.
THE REJECTIONS
The claims stand rejected as follows: claims 2-12, 28-34, 39, 41 and
45-79 under 35 U.S.C. § 112, first paragraph, enablement requirement, and
claims 39 and 41 under 35 U.S.C. § 112, fourth paragraph, as being
dependent from a canceled claim.
