Abstract: An athermal package (500) for fiber photonic devices includes a ferrule to attach the optical fiber(200) to the package. The ferrule has an opening to receive the optical fiber. The ferrule is collapsed to attach the optical fiber to the athermal package. Alternatively, the athermal package (500) uses adhesive bonds (503, 504) disposed in pockets (506, 507) of the package. The pockets have a narrow end and a wide end, with the narrow ends facing each other. The adhesive bonds are disposed in the pockets in contact the narrow ends of the pockets but not with the wide ends. The narrow ends physically confine the adhesive bonds so that if the bonds expand or contract due to environmental conditions (or the curing process), the adhesive either expands or contracts near the wide ends of the pockets. This allows the strain on the optical fiber segment between the bonds to remain substantially constant.

Abstract: A platform comprising a support providing a controlled thermal expansion coefficient in a given direction. The support is formed of a material having a first thermal expansion coefficient and is connected to a body having a second thermal expansion coefficient. The first thermal expansion coefficient is different from the second thermal expansion coefficient, such that a change in temperature causes a relative change in the dimensions of the support and the body in a direction perpendicular to the said given direction, thereby resulting in the variation of a force applied to the support by the body in the direction perpendicular to the said given direction to control the resultant expansion coefficient in the said direction. The use of the platform for mounting optical elements such as fibre Bragg gratings, Fabry-Perot cavities or telescopes is disclosed.

Abstract: Ceramic monoliths are described which exhibit tunable coefficients of thermal expansion from about -5 to -11 x10 DEG C near ambient temperatures. These two-phase ceramics, which are fabricated, for example, by reactive sintering of WO3 and ZrO2, consists of a matrix of ZrW2O8 with inclusions of ZrO2 having diameters less than 10 mu m. Additives may increase the density of the monoliths to greater than 98% of the calculated density. Green body densities, pre-sintered particle size distribution, sintering atmosphere, microstructure, and mechanical properties are discussed. These ceramics may be used as substrates for thermally compensating fiber Bragg gratings.

Abstract: A temperature compensated optical device includes a compression-tuned glass element (10) having a Bragg grating (12) therein, a compensating material spacer (26) and an end cap (28) all held within an outer shell (30). The element (10), end cap (28) and shell (30) are made of a material having a low coefficient of thermal expansion (CTE), e.g., silica, quartz, etc. And the spacer (26) is made of a material having a higher CTE, e.g. metal Pyrex3, ceramic, etc. The material and length L5 of the spacer (26) is selected to offset the upward grating wavelength shift due to temperature. As temperature rises, the spacer (26) expands faster than the silica structure causing a compressive strain to be exerted on the element (10), which shifts the wavelength of the grating (12) down to balance the intrinsic temperature induces wavelength shift up. As a result, the grating (12) wavelength is substantially unchanged over a wide temperature range. The element (10) includes either an optical fiber having at least one Bragg grating (12) impressed therein encased within and fused to at least a portion of a glass capillary tube or a large diameter waveguide (or cane) with a grating (12) having a core (11) and a wide cladding, which does not buckle over a large range of compressive axial strains. The element may have a "dogbone" shape to amplify compressive strain on the grating (12). The device (8) may also be placed in an axially tunable system that allows the wavelength to be dynamically tuned while remaining athermal. In addition to a grating, the device may be an athermal laser, DFB laser, etc. Also, the entire device (8) may be all made of monolithic glass materials.
