Publication number: 20030002847Abstract: Manufacturing Technique for Optical Fiber Array An improved manufacturing technique for optical fiber arrays employs optical feedback in a partially assembled unit using an inspection camera. This allows immediate reworking of a problematic part. In the present invention, a video microscope is used to check the alignment of the optical fiber array during the manufacturing process. After the optical fiber array has been glued or otherwise affixed, then an optical device may be used to measure the performance of the glued assembly.Type: ApplicationFiled: June 28, 2001Publication date: January 2, 2003Inventors: Eyal Shekel, Eli Rephaeli

Publication number: 20030002777Abstract: Two N-channel deflector modules, both located in the same layer or plane of an assembly, direct polarized beams toward a polarization beam splitter. A half wave plate is interposed between one of the deflector modules and the polarization beam splitter. The polarization beam splitter combines the two beams into a single output beam, without loss of optical power, comprising 2N channels, each of which can carry a unique data stream. In alternate embodiments the group of two deflector modules and a polarization beam splitter can be stacked, optionally in combination with layers comprising a single deflector module and polarization beam splitter or mirror.Type: ApplicationFiled: July 2, 2001Publication date: January 2, 2003Inventors: Shlomo Ruscchin, Eyal Shekel, Michael Rudman
