• Manufacturing Low Insertion Loss Fiber-Lens Elements Fiber-lens alignment is a required production step for numerous fiber optic components, and the goal is to minimize the insertion loss as the light passes through the fiber-lens pair. Profiling the light emitted from the lens-fiber pair is important for developing processes that can be automated and have a high degree of repeatability. This paper describes how Photon can provide solutions for these processes. Derrick Peterman, Ph.D., John Fleischer and Dan C.

• The Scanning Goniometric Radiometer A Revolutionary Technique for Characterizing Divergent Light Sources: Laser Diodes, VCSEL's, Optical Fibers, Waveguides, LED's,... Measurements of the irradiance pattern of light sources has traditionally been performed using instrumentation systems commonly referred to as "goniometers" or "goniophotometers". These systems comprise a detector and a fixture for holding the source, and the measurement is made either by moving the detector about the source at a fixed radius or by rotating the source on a rotation stage with the detector stationary. With these systems, the time required to measure the far field pattern along a single azimuth ranges typically from a few minutes up to an hour. These time constraints made it difficult if not practically impossible to perform more complete characterization of the irradiance pattern of optical sources. An improvement to these methods, the "scanning goniometric radiometer", offers up to 3 or more orders of magnitude increase in measurement speed, up to 2 orders of magnitude improvement in angular sampling resolution, and a measurement field-of-view up to 360°. Details of the new technique, and application examples for measurements fo laser diodes, VCSEL's, LED's and optical fiber will be presented. by Jeffrey Guttman, Ph.D. — Presented at the April 23, 2002 meeting of the Santa Clara Valley (Silica Valley, California) IEEE Lasers & Electro-Optics Society (LEOS)
