A nonlinear optical system comprises a metallic film having a first side and a second side. The nonlinear optical system further comprises a regular array of slits in the metallic film. The slits connect the first and second sides of the metallic film. The array is configured to selectively transmit through the metallic film light having frequencies of a selected frequency band. The nonlinear optical system still further comprises a nonlinear optical material situated within the slit.

Nonlinear and gain optical devices formed in metal gratings

Apparatus including flexible line extending along a length. Flexible line includes first charge carrier-transporting body, photosensitive body over first charge carrier-transporting body, and second charge carrier-transporting body over photosensitive body. Each of first and second charge carrier-transporting bodies and photosensitive body extend along at least part of length of flexible line. Photosensitive body is capable of near-infrared or visible light-induced generation of charge carrier pairs. Second charge carrier-transporting body is at least semi-transparent to near-infrared light or visible light.

The present invention relates to a polymeric composition of matter. The composition includes at least one polymer matrix and plurality of quantum dots distributed therein. The polymer may be a perfluorocyclobutane polymer having high optical transmission at telecommunications wavelengths. The quantum dots may include cap compounds to increase the solubility of the quantum dots in the composition. Typical cap compounds include aromatic organic molecules. Optical devices including waveguides may be fabricated from the polymeric compositions of the invention.

Techniques for producing a glass structure having interconnected macroscopic pores, employing steps of filling polymerizable glass precursors into pores in a polymeric structure having interconnected macroscopic pores; polymerizing the precursors; and decomposing the polymers to produce a glass oxide structure having interconnected macroscopic pores. Further techniques employ steps of exposing portions of a photosensitive medium including glass precursors to an optical interference pattern; polymerizing or photodeprotecting the exposed portions and removing unpolymerized or deprotected portions; and decomposing the polymerized or deprotected portions to produce a glass structure having interconnected macroscopic pores. Techniques for filling pores of such glass structure with a material having a high refractive index, and for then removing the glass structure. Structures can be produced having interconnected macroscopic pores and high refractive index contrasts, which can be used, for example, as photonic band gaps.
