摘要： A rare-earth doped glass waveguide is optically pumped to produce superfluorescent light. The waveguide is formed in a glass substrate. The pump light is input to a first end of the optical waveguide, and the output is emitted from the other end. A grating formed on the waveguide near the output end reflects the pump light to separate the pump light from the output light.

摘要： An optical device is disclosed which provides wavelength multiplexing/demultiplexing utilizing a plurality of focusing Bragg reflectors. Each Bragg reflector includes a plurality of confocal (i.e., common foci) elliptical grating lines, with the exit/entrance ports of the input/output waveguides located at the foci of the ellipse. By virtue of the elliptical design, the signal propagating outward from the exit port of the input waveguide will be reflected by the appropriate Bragg reflector and focused into the entrance port of the appropriate output waveguide. When each Bragg reflector exhibits a different ellipticity, but shares one common focal point, optical multiplexing/demultiplexing may be achieved. Optical filtering may be achieved when all Bragg reflectors are designed to have common foci.

摘要： Divided function optical component, for optical telecommunications, of the type comprising optical fibers in conjugate object-image positions for regrouping or separating the light rays according to a given function. The component comprises simultaneously several groups of conjugate object-image fibers relative to the same regrouping or separation function. All the fibers are positioned in the same weak aberration area.
