Abstract: 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.

Abstract: A method for making a double-sided microlens mold and microlens array mold is described which utilizes a spinning half radius diamond cutting member operated in a plunge cut in a technique similar to milling to cut the optical surface into a diamond turnable material.

Abstract: 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.

Abstract: A method is disclosed for making deep microstructures in photoresist. The method utilizes a pool of photoresist on top of a transparent substrate and the laser is located below the substrate. Structures are created in the photoresist by transmitting the laser light through the substrate up into the photoresist. Since the photoresist does not have to be spin coated onto the substrate, very thick layers of photoresist can be used while the thickness uniformity is determined by the substrate surface. Alternately, a contoured substrate can be used while producing uniform structures.

Abstract: An approach for performing an address look-up in a relatively high latency network is disclosed. A terminal receives a query from a local host requesting address information. The terminal includes a memory that stores the address information, and a processor that is coupled to the memory and is configured to determine whether the address information associated with the query is stored in the memory. The processor selectively transmits the address information to the local host in response to the determination. The system also includes a server that communicates with the terminal over the network. The server receives the query from the terminal and transmit the address information corresponding to the query to the terminal. The present invention has particular applicability to a communications system that employs a satellite network.
