摘要： A compression-tuned bragg grating includes a tunable optical element 20,600 which includes either an optical fiber 10 having at least one Bragg grating 12 impressed therein encased within and fused to at least a portion of a glass capillary tube 20 or a large diameter waveguide grating 600 having a core and a wide cladding. Light 14 is incident on the grating 12 and light 16 is reflected at a reflection wavelength &lgr;1. The tunable element 20,600 is axially compressed which causes a shift in the reflection wavelength of the grating 12 without buckling the element. The shape of the element may be other geometries (e.g., a “dogbone” shape) and/or more than one grating or pair of gratings may be used and more than one fiber 10 or core 612 may be used. At least a portion of the element may be doped between a pair of gratings 150,152, to form a compression-tuned laser or the grating 12 orgratings 150,152 may be constructed as a tunable DFB laser. Also, the element 20 may have an inner tapered region 22 or tapered (or fluted) sections 27. The compression may be done by a PZT, stepper motor or other actuator or fluid pressure.

摘要： An optical filter, including a Bragg grating, is compression tuned such that when under one compressional load (or no load) the grating has a first profile and under a second compressional load the grating has a second profile. One application is to allow the grating filter function to be parked optically between channels of a WDM or DWDM optical system.

摘要： A tunable optical filter filters is provided that has a pair of tunable Bragg grating units optically coupled to respective ports of a 4-port circulator for filtering a selected wavelength band or channel of light from a DWDM input light. Each grating unit includes an array of Bragg gratings written or embedded within a respective tunable optical element to provide a tunable optical filter that functions over a wide spectral range greater than the tunable range of each grating element. The reflection wavelengths of the array of gratings of each respective grating element is spaced at a predetermined spacing, such that when a pair of complementary gratings of the grating elements are aligned, the other complementary gratings are misaligned. Both of the optical elements may be tuned to selectively align each complementary grating over each corresponding spectral range.

摘要： A fluid diffusion resistant tube-encased fiber grating pressure sensor includes an optical fiber 10 having a Bragg grating 12 impressed therein which is encased within a sensing element, such as a glass capillary shell 20. A fluid blocking coating 30 is disposed on the outside surface of the capillary shell to prevent the diffusion of fluids, such as water molecules from diffusing into the shell.

摘要： A fused tension-based fiber grating pressure sensor includes an optical fiber having a Bragg grating impressed therein. The fiber is fused to tubes on opposite sides of the grating and an outer tube is fused to the tubes to form a chamber. The tubes and fiber may be made of glass. Light is incident on the grating and light is reflected from the grating at a reflection wavelength &lgr;1. The grating is initially placed in tension as the pressure P increases, the tension on the grating reduced and the reflection wavelength shifts accordingly. A temperature grating may be used to measure temperature and allow for a temperature-corrected pressure measurement.

摘要： A compression-tuned fiber Bragg grating based reconfigurable wavelength add/drop module has a compression force assembly and an all-glass Bragg grating compression unit having gratings spaced along an axis of compression. The compression force assembly responds to a control electronics signal containing information about a selected wavelength of a channel to be added to or dropped from an optical traffic signal, for providing a compression force applied along the axis of compression. The compression unit responds to the optical traffic signal and the compression force, for providing an all-glass Bragg grating compression unit optical signal having the selected wavelength of the channel to be added to or dropped from the optical traffic signal. The compression unit optical signal may include either the traffic with an added reflected channel(s), or a dropped reflected channel(s). The compression unit is a “dogbone” structure having either a glass tube with an optical fiber fused therein, or a single large diameter waveguide having a core. The core of the optical fiber or waveguide has the gratings spaced therein. The axis of compression is parallel with the longitudinal axis of the dogbone structure.

摘要： An optical filter, including a pair of Bragg grating units optically coupled to respective ports of a circulator, is provided for filtering a selected wavelength band of light from a DWDM input light. Each grating unit includes a respective tunable optical element, which have a reflective element, such as a Bragg grating. Generally, one grating unit filters a selected wavelength band of light and reflects the selected wavelength band to the other grating unit, which reflects a portion of the reflected wavelength band to an output of the optical filter. This double reflection of the selected wavelength band provides an optical filter having an effective filter function that is equal to the product of the individual filter functions of the grating units. To create a desired effective filter function, the gratings may be written to have different filter functions or grating profiles. One or both of the grating units may also be tunable to selectively create, tailor, shape or change the effective filter function of the optical filter in response to a control signal by offsetting the reflection wavelengths of the gratings, having different grating profiles.

摘要： A tunable dispersion compensating device includes a grating element in the form of a bulk or large diameter waveguide, having an outer cladding disposed about an inner core. The grating element may be etched, grounded or machined to form a generally “dog bone” shape, wherein the end portions of the grating element has a larger diameter than the center portion disposed therebetween. A chirped grating is written or impressed within the portion of the core disposed in the center portion of the grating element. The center portion is tapered to allow different stresses to be applied along the grating length when the grating element is compressed longitudinally by force F, and thereby vary chirp of the grating to tunably compensate for dispersion.
