    摘要： A variable optical attenuator comprises a portion of a waveguide through which optical energy can propagate having a side surface through which optical energy can be extracted; a layer of thermo sensitive material having controllable optical properties, covering the side surface of the portion; a helicoidal heating element wrapped around the waveguide and covering at least the layer. The helicoidal heating element can be used to control the optical properties of the material by inducing a thermal transfer profile on the material using the heat dissipation of the heater through the material; wherein a wave propagation in the waveguide is influenced by the optical properties of the material controlled by the heating element. The heating element can also have a measurable temperature coefficient; a controller for controlling the temperature of the heating element as a function of the temperature coefficient; wherein the temperature of the heating element can be controlled without using an additional temperature probe. And the heating element can also be used to control the curing of the material using the heat dissipation of the heater through the material, thereby providing a mechanical armature for the material and the waveguide; wherein the mechanical armature solidifies the attenuator.

    摘要： Described is a composite liquid crystalline mixture having a low refractive index and a chemical reactive power that makes it capable of minimizing an anchoring energy when in contact with silica. This mixture comprises: (a) low ordinary refractive index nematic liquid crystal of a single type or a mixture of low ordinary refractive index nematic liquid crystals of different types; (b) at least one reagent compound capable of reducing the anchoring energy via a chemical shielding process and from which originates a decoupling effect with a glass interface leading to the reduction of the anchoring energy and appropriately orienting a liquid crystal director at this interface; and (c) at least one low refractive index additive having a relatively low viscosity. The above mixture is useful in waveguide tuning applications.

    摘要： We propose a dynamically tunable electro-optic cladding using our proprietary electro-optic material, applied to various circular and planar wave-guides along with specific electrode configuration and excitation electric field format appropriate to that material. Based on the evanescent field coupling phenomena, the proposed device may be used in variable optical attenuators, tunable filters and couplers, etc. Different design of applied electrodes and optical properties of controllable refractive index materials allow polarization dependent or independent, as well as direct or inverse operation regimes of proposed devices.

    摘要： A material composition for optically coupling two optical components, a method for making such a coupling and the resulting device are provided. The material composition includes a first material system polymerizable by light, and a second material system having a refractive index smaller than that of the first material system after its polymerization. The second material system is miscible with the first prior to its polymerization, but repulsed by it afterwards. The material composition is injected between two optical components, such as a light source and waveguide or two waveguides, and exposed to light beams from both sides to generate a light guiding channel therebetween. The transverse refractive index profile in the coupling region is W-shaped.

    摘要： In a method for coupling an optical waveguide to a light emitting diode (LED) within a resin case, an input end of the optical waveguide is mounted proximal to a surface formed in the resin case parallel to a light-emitting face of the LED. The optical waveguide and the resin case can be bonded by a light or thermally curable resin that is applied and subsequently solidified. The light or thermally curable resin may be a photopolymer sensitive to light emerging from the waveguide. An automated coupling system is provided to optimize the coupling conditions using the in-coupled light efficiency feedback and controller. Finally a method is described allowing the coupling efficiency to be controlled using external excitation forces or light intensity variations, using electro-optic, magneto-optic, thermo-optic, light polarization sensitive or nonlinear properties of the filler material used between the resin case and waveguide.
