  • Patent number: 6625351
    Abstract: Collimating microlenses are “printed” from optical polymeric materials on the ends of optical fibers using ink-jet technology. In one embodiment the optical fibers are inserted into a collet, a stand-off distance from the open upper end of the collet. The open upper end is filled with optical fluid and a microlens is formed thereon to collimate light exiting the fiber through the microlens. In another embodiment optical fibers from a “ribbon” are separated and installed into a ferrule having multiple openings therethrough. In the same manner as in the collet embodiment, the ferrule openings serve as a mold for the lens formation with the end of the fiber being located at the focal distance of the lenslet formed in an on the ferrule. A non-wetting coating can serve to control spreading of the fluid optical material and allow lens radius control as well. The microlenses are hardened after formation.

  • Publication number: 20010048968
    Abstract: A process is disclosed which utilizes ink-jet printing of optical polymeric fluids to produce microlenses on a substrate having an axial gradient index of refraction. Two optical polymeric fluids are used, one having an index of refraction higher than the other. A base portion of the microlens is printed using the lower index of refraction material and a cap portion of the microlens is printed over the base portion to produce a radiused formed microlens. Inter-diffusion of the base portion and top or cap portion creates a generally uniform gradient diffusion zone in the axial (vertical) direction wherein the lower boundary of the zone has the index of the base portion and the upper boundary of the zone has the index of the top portion. After a sufficient gradient diffusion zone is formed, the formed microlens is solidified by curing or other means to stop any further diffusion. The microlenses may be formed as individual lenses on a optical substrate or as an array of microlenses.
