  • Patent number: 6404952
    Abstract: An optical communication system with dispersion compensation uses transverse mode transformers and a chromatic dispersion compensation optical fiber. A low order spatial mode optical signal from a communication fiber is transformed by a transverse mode transformer into a higher order spatial mode before being injected into a chromatic dispersion compensation optical fiber. The optical signal exiting the compensation fiber is then transformed back to a lower order spatial mode before being injected into a second communication fiber.

  • Patent number: 6360045
    Abstract: The invention relates to methods and apparatus for transmitting an optical signal having optical energy. The system, in one embodiment, includes at least one transmission span including an optical waveguide. The transmission span transmits substantially all of the optical energy in a single high order spatial mode. The optical waveguide, in one embodiment, has a dispersion and a dispersion slope for a given transmission bandwidth. In another embodiment, the invention further relates to an optical transmission system which includes a spatial mode transformer positioned to receive an optical signal. The spatial mode transformer transform the optical energy of the optical signal from a low order spatial mode to a high order spatial mode. The system further includes an optical transmission waveguide in optical communication with a spatial mode transformer, and the optical transmission waveguide transmits substantially all of the optical energy in the high order spatial mode.

  • Patent number: 6340248
    Abstract: The present invention relates to a method for enabling reliable, consistent alignment of a beam of light eating the end of an optical fiber, which has been cut at a non-perpendicular angle, with a collimating lens. The method involves utilizing a spherical shape to generate two bores in the object which intersect the center at a predetermined angle. The predetermined angle is equivalent to the angle of the light beam exiting the end of the optical fiber.
