Quality Review Method For Optical Components Using A Fast System Performance Characterization
US Patent:
6781698, Aug 24, 2004
Filed:
Sep 9, 2002
Appl. No.:
10/237325

Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
G01B 902
US Classification:
356477
Abstract:
A method for screening the quality of an optical component including the step of simulating the performance of the optical component. The step of simulating includes the step of measuring the optical phase of the optical component, wherein the step of measuring comprises indirectly measuring the optical phase of the optical component using a scanning laser having a scanning step size and a modulation frequency such that /. The light throughput R of the optical component is then measured. A transfer function H as a function of optical frequency is constructed where H()=R()exp[j ()], and the performance is simulated using the measured value of the optical phase and the light throughput into the transfer function.

Tunable Talbot Interferometers For Fiber Bragg Grating Writing
US Patent:
6915044, Jul 5, 2005
Filed:
Jul 15, 2003
Appl. No.:
10/619776
Inventors:
Michael R. Matthews - Austin TX, US
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
G02B006/34
US Classification:
385 37, 385 10, 385 14, 385 15, 359570
Abstract:
A tunable interferometer for creating gratings of variable periodicity in an optical waveguide is disclosed. The interferometer includes a beam splitter for producing first and second write beams from an input beam. First and second reflectors receive the first and second write beams, respectively, from the beam splitter and direct the first and second write beams to intersect at a fixed location. The angle of intersection of the first and second write beams is a function of impingement locations of the first and second write beams on the first and second reflectors. The impingement locations of the first and second write beams on the first and second. reflectors may be varied to vary the angle of intersection at the fixed location.

G01R 27/08, G06F 19/00
US Classification:
324693, 702 34, 702 35, 324700
Abstract:
A detection system for monitoring an engineered structure includes an array of sensors disposable in a predetermined pattern on the engineered structure and disposable between a surface of the engineered structure and a protective coating substantially covering the surface. The detection system also includes a data acquisition system in communication with the array of sensors for retrieving data from the sensors. The array of sensors can provide data corresponding to at least one of a degree of cure of the protective coating, a health of the cured protective coating, and a corrosion rate of the engineered structure at each of the sensors.
Method And Apparatus For Alignment Of A Polarization Maintaining Optical Fiber
US Patent:
2004019, Oct 7, 2004
Filed:
Apr 4, 2003
Appl. No.:
10/406927
Inventors:
Michael Matthews - Austin TX, US
International Classification:
G02B006/27
US Classification:
385/011000
Abstract:
A device and method in accordance with the present invention align the polarization of an incoming light wave to the principal axis of a polarization maintaining (PM) optical fiber. Light is launched from the broadband source travels through a beam splitter to a polarizer, a polarization control device, a signal transmission medium and a birefringent medium having at least one partially reflective region including a cleaved and polished end face of the fiber or a Bragg grating written into a length of PM fiber. The reflected light is then used to align the polarization of the light to the birefringent axis of the PM fiber.
