摘要:
The present invention relates to a photonic device comprising a plurality of nanostructures that extend from a substrate, each nanostructure comprising a generally longitudinal nanostructure body formed of a semiconductor material. Each nanostructure has a proximal end portion of a first crystal lattice structure and a distal end portion of a second crystal lattice structure that is expanded relative to the proximal end portion. Each nanostructure further comprises an optically active material optically associated with the distal end portion to form a heterojunction therebetween. The present invention further relates to a method of making the disclosed nanostructures.
摘要:
A method of forming an array of selectively shaped optical elements on a substrate, the method including the steps of providing the substrate, the substrate having an optical layer placed thereon; placing a layer of particles on the optical layer; performing an etching cycle. The cycle includes the steps of: etching the layer of particles, using a first etching process so as to reduce the size of the particles within the layer, then; simultaneously etching the optical layer and the layer of particles, using a second etching process, the further reducing particles forming a mask over areas of the optical layer to create discrete optical elements from the optical layer.

The present invention relates to a method of forming polymer substrate with variable refractive index sensitivity, the method comprising the steps of: (a) contacting a metal-coated patterned mold with a polymer substrate at a temperature sufficient to deform said polymer substrate to thereby deposit a patterned mask of a metal film on the polymer substrate; and (b) etching away portions of said polymer substrate not covered by said patterned mask under conditions to form a region of variable refractive index sensitivity on said polymer substrate.
