Sep 28, 1998

Appl. No.:

09/161944

Inventors:

Dwayne L. LaBrake - Cedar park TX

Assignee:

3M Intellectual Properties Company - Saint. Paul MN

International Classification:

G02B 634

US Classification:

385 37, 385123, 372102, 359130

Abstract:

A long length continuous phase Bragg reflector and the method and an apparatus for writing the gratings into an optical fiber. The method includes the steps of providing a photosensitive optical fiber and a writing beam. A periodic intensity distribution of period is created from the writing beam and the optical fiber is translated relative to the intensity distribution at a velocity v(t). The intensity of the writing beam is modulated as a function of time at a frequency f(t), where. v(t)/f(t). The intensity of the writing beam is varied further to control the envelope of the refractive index profile to write apodized gratings. The gratings measure at least 2. 5 meters in length.

Abstract:

A method for manufacturing an optical fiber refractive index grating. The method comprises the steps of, providing a substantially twist-free length of an optical fiber between a first spool and a second spool before attaching the first spool and the second spool to a support having a first surface opposite a second surface. The support and spools provide a filament organizer including the first spool as a lockable spool and the second spool as a rotary spool. The filament organizer further comprises a tensioner coupled to the rotary spool to apply tension to at least a central portion of the length of an optical fiber disposed between the lockable spool and the rotary spool. After removing a buffer coating from the central portion of an optical fiber and applying a controlled tension to the central portion of the optical fiber, changes are made to the refractive index characteristics of the central portion during exposure to an interference pattern of high intensity actinic radiation, to produce the refractive index grating.

International Classification:

G02B 600

US Classification:

385135, 385137, 242159, 242169

Abstract:

A filament organizer comprises a support having a first surface opposite a second surface and further includes a lockable spool and a rotary spool adjacent to the first surface of the support. The organizer has a tensioner attached to the second surface of the support for attachment to the rotary spool by a tension wire to apply tension thereto to transmit tension to a filament disposed between the lockable spool and the rotary spool. Selective reduction in tension on a filament is possible using a tension relief assembly attached to the support. A stacked configuration of a plurality of filament organizers may be formed by suitable alignment of supports.

Abstract:

The present invention provides a method of patterning a substrate, the method including, inter alia, forming a multi-layered structure on the substrate formed from first, second and third materials. The first, second and third materials are exposed to an etch chemistry, with the first and second materials having a common etch rate along a first direction, defining a first etch rate, and the first and third materials having a similar etch rate along a second direction, transversely extending to the first direction, defining a second etch rate. Typically, the etch rate is selected to be different in furtherance of facilitating control of the dimensions of features formed during the etching process.
