  • Patent number: 9782814
    Abstract: A composite structure includes a base and an auxiliary portion of dissimilar materials. The auxiliary portion is shaped by stamping. As the auxiliary portion is stamped, it interlocks with the base, and at the same time forming a desired structured feature on the auxiliary portion, such as a structured reflective surface, an alignment feature, etc. With this approach, relatively less critical structured features can be shaped on the bulk of the base with less effort to maintain a relatively larger tolerance, while the relatively more critical structured features on the auxiliary portion are more precisely shaped with further considerations to define dimensions, geometries and/or finishes at relatively smaller tolerances. The auxiliary portion may include a composite structure of two dissimilar materials associated with different properties for stamping different structured features.

  • Patent number: 9733425
    Abstract: A process for producing an optical fiber including a glass fiber, a primary resin coating layer which covers the periphery of the glass fiber, and a secondary resin coating layer which covers the periphery of the primary resin coating layer, wherein the primary resin coating layer is formed by curing a curable resin composition which includes one or more oligomers, one or more monomers, and a reaction initiator, the curable resin composition containing a one-end-capped oligomer in an amount of 30% by mass or larger based on all the oligomers. The optical fiber produced by this production process does not deteriorate in low-temperature transmission loss, because the primary resin coating layer is inhibited from generating voids even when having a low Young's modulus.

The right angle waveguide is a photonic crystal formed from first dielectric rods having a high refractive index arranged in a background dielectric having a low refractive index according to a square lattice. In the photonic crystal, one row and one column of the first dielectric rods having the high refractive index are removed to form the right angle waveguide. A second dielectric rod having a high refractive index is arranged at a corner of the right angle waveguide, the second dielectric rod being the compensation scattering rod. The first dielectric rods are square rods having the high refractive index. The right angle waveguide has extremely low reflectance and a very high transmission rate, and facilitates large-scale optical path integration.
