摘要： A thermally tunable optical fiber device comprises a length of optical fiber including a device disposed within a microcapillary heater. The microcapillary heater can include a thin film resistive heater. The fiber itself can optionally include a thin film resistive heater overlying the device, and a plurality of nested microcapillary tubes can optionally provide a plurality of successive concentric heaters overlying the device. The heaters films can be films with uniform, tapered or periodically varying thickness. The heaters can be single layer or multiple layer. Multiple layer films can be superimposed with intervening insulating layers or plural layers can be formed on different angular regions of the microcapillary. Thus one can provide virtually any desired temperature versus length profile along the fiber device.

摘要： In accordance with the invention, an optical fiber grating device is made by providing a fiber with an electrically actuable component optically responsive to voltage or current and a plurality of conductive elements to locally activate the component and thereby to produce local optical perturbations in the fiber. In a preferred embodiment, a fiber is provided with a core of liquid crystal material and a plurality of periodically spaced microelectrode pairs. Application of a voltage to the microelectrodes results in a periodic sequence of perturbations in the core index which produces a grating. When the voltage is switched off, the grating switches off. Other embodiments utilize helical conductive elements.

摘要： A unique waveguide structure is provided in which the waveguide contains individual scattering elements that are capable of being tuned to provide local refractive index variations, e.g., on a micron scale—which is on the order of wavelengths typically used for communication system. According to the invention, the waveguide contains a core region, a cladding region, and a solid or liquid material having the tunable scattering elements dispersed therein, where the material is disposed within the core and/or cladding regions, and/or on the exterior of the cladding region. Useful scattering elements include, for example, liquid crystals dispersed in a polymer (polymer-dispersed liquid crystals—PDLC) or electrophoretic particles dispersed in a liquid medium.

摘要： In accordance with the invention, an optical waveguide grating with an adjustable optical spacing profile comprises a waveguide grating in thermal contact with one or more resistive film coatings. A coating extends along the length of the grating and its local resistance varies along the length of the grating. In one embodiment, a plurality of overlaping coatings are chosen so the resistance variation of each is different, thereby permitting a variety of heat generation profiles to be effected by independent control of the coatings. The different heat generation profiles, in turn, proportionately change the grating geometric spacing and local refractive index along the grating length, providing the desired adjustable optical spacing profile. Other embodiments use resistive films with abruptly changing or periodically changing heating variation.

摘要： In accordance with the invention, an electrically modifiable optical fiber grating device is made by providing a fiber including a grating and forming a plurality of electrically conductive elements along the grating. In response to an electrical signal, the conductive elements modify the grating. In a preferred embodiment, a fiber grating is provided with a plurality of heating elements spaced to selectively heat different portions of the grating. This chirps the spacing between elements of the grating and thereby increases the bandwidth of the device.

摘要： Provided are devices, and related methods, for controlling curvature of an array of optical components on, embedded, or partially embedded in, a deformable substrate. The array of optical components, in an aspect, comprises a deformable substrate having a contact surface and an array of mechanically interconnected optical components supported by the contact surface. An actuator is operably connected to the contact surface, wherein the actuator variably controls a curvature of said contact surface. The contact surface may have a curvature that spans concave to convex, which is tunable. In an aspect, the array of optical components is part of an optical device, such as a camera with a continuously adjustable zoom whose focus is maintained by adjusting a photodetector array curvature. In an aspect, the method is adjusting the curvature of a substrate that supports the array of optical components by applying a force to the substrate.

摘要： In a method of printing a transferable component, a stamp including an elastomeric post having three-dimensional relief features protruding from a surface thereof is pressed against a component on a donor substrate with a first pressure that is sufficient to mechanically deform the relief features and a region of the post between the relief features to contact the component over a first contact area. The stamp is retracted from the donor substrate such that the component is adhered to the stamp. The stamp including the component adhered thereto is pressed against a receiving substrate with a second pressure that is less than the first pressure to contact the component over a second contact area that is smaller than the first contact area. The stamp is then retracted from the receiving substrate to delaminate the component from the stamp and print the component onto the receiving substrate. Related apparatus and stamps are also discussed.
