20100189402 | Method for Effective Refractive Index Trimming of Optical Waveguiding Structures and Optical Waveguiding Structures - A method for trimming an effective refractive index of optical waveguiding structures made for example in a high refractive index contrast material system. By compaction of cladding material in a compaction area next to patterns or ridges that are formed in the core material for realizing an optical waveguiding structure, the effective index of refraction of the optical waveguiding structure can be trimmed. Thus, the operating wavelength of an optical component comprising such an optical waveguiding structure can be trimmed. An optical waveguide structure thus obtained is also disclosed. | 07-29-2010 |

The method also comprises, while applying the selected liquid crystal orienting condition, polymerizing the polymerisable liquid crystal cladding layer of the selected photonic device, thus obtaining a polymerized liquid crystal on the selected photonic device. | 05-15-2014 |
20140185042 | MOLECULAR ANALYSIS DEVICE - In the present invention, a molecular analysis device comprises a substrate, and a waveguide with a planar integrating element and filter or reflector element adjacent thereto is disposed on the substrate. The waveguide comprises a coupling means configured for coupling a predetermined frequency range of laser radiation into the waveguide. At least one metallic nanostructure is disposed on or adjacent to the planar integrating element, at least one metallic nanostructure is configured such that the field intensity and the gradient of the laser radiation, that is coupled into the waveguide, are enhanced over a sufficiently large volume around the nanostructure to simultaneously cause plasmonic based optical trapping of analyte(s) in a medium, and plasmonic based excitation of the particles to produce Raman scattered radiation. A Raman scattered radiation collection means is disposed on the substrate for collecting said Raman scattered radiation produced by the particles. | 07-03-2014 |
20140363127 | Integrated Photonics Waveguide Grating Coupler - A photonic integrated device comprises a waveguide embedded in a photonic substrate.
