A laser array and method of making same has precision fiducial marks that aid in the alignment of the laser array. The invention requires forming additional optical features adjacent to the laser array that is used to write fiducial marks on an opposite surface in the medium containing the laser array. Fiducial marks are formed when high intensity collimated beams of light are directed through the optical features onto a treated portion of the transparent medium. Fiducial accuracies of 1 micron are possible by using this approach.

Laser array and method of making same

A method of forming fiducial marks on a micro-sized article has at least one optical feature adjacent the micro-sized article that focuses a collimated beam of light onto a surface opposite the mounting surface of the micro-sized article. Fiducial mark is formed on the surface that enables precise alignment of the micro-sized articles.

A fiber optic array and method of making same has precision fiducial marks that aid in the alignment of the fiber optic array. The invention requires forming additional optical features adjacent to the fiber optic array that is used to write fiducial marks on an opposite surface in the medium containing the fiber optic array. Fiducial marks are formed when a high intensity collimated beam of light is directed through the optical features onto a treated portion of the transparent medium. Fiducial accuracies of 1 micron are possible by using this approach.

Fiber optic array and method of making same

A method of manufacturing a microlens array requires at least two fiducial marks formed on a surface of a transparent medium opposite the microlens array. Additional optical features formed on the transparent medium adjacent the microlens array enables precise locationing of fiducial marks on an opposing surface when such surface is exposed to a collimated beam of light. The location of fiducial marks using the method of the invention is about 1 micron or less.

Method and manufacturing a precisely aligned microlens array

A double-sided microlens array and method has a plurality of first microlenses on a first surface opposite a plurality of second microlenses on a second surface of a transparent medium. At least two optical features are arranged on either of the first or second surfaces to form fiducial marks on the opposing surface in the transparent medium. The fiducial marks enable precise alignment of the microlenses in the first and second plurality of microlens arrays.

Double-sided microlens array and method of manufacturing same

A microlens array has a plurality of microlens supportedly arranged on a first surface of a transparent medium. At least two optical features are formed on a second surface opposite the first surface. Fiducial marks are formed on the second surface by a beam of collimated light directed onto the optical features and focused onto the second surface. Fiducial marks enable precise alignment of the microlenses in the microlens array.
