An implantable optical sensor () comprising a substrate () and at least one optical microstructure () for evanescent field sensing integrated with the substrate (), the at least one optical microstructure () being positioned to form an optical interaction area () on a part of a surface () of the substrate (), the optical assembly () further comprising a thin protective layer () covering at least the optical interaction area (), the thin protective layer () being in a predetermined material with corrosion-protection characteristics and having a predetermined thickness, so as not to affect the evanescent field sensing.

Implantable optical sensor

A method for testing an optical assembly () which has an optical microstructure () integrated with a substrate (). The optical microstructure () is positioned to form an external optical interaction area () on a part of a surface () of the substrate (). A cover cap () seals at least a part of the surface () of the substrate () adjacent to the optical microstructure () to obtain a sealed cavity (). An optical feedthrough () is integrated in the substrate () to form an external communication path from within the sealed cavity (). The optical feedthrough () allows communication of a physical parameter value which is measured inside the sealed cavity () to outside the sealed cavity (). The physical parameter value is associated with a measure of hermeticity of the sealed cavity ().

Hermeticity testing of an optical assembly

An on-chip broadband radiation source, and methods for its manufacture such that a photonics IC comprises an optical waveguide such as a semiconductor waveguide, a thin III-V material membrane with absorption capability for absorbing an optical pump signal induced in the waveguide. The III-V membrane comprises a LED implemented therein. The photonics IC also comprises a coupling means between the waveguide and the membrane. The device provides a broadband radiation source at a wavelength longer than the wavelength of the transferred radiation. The broadband signal can then be coupled out through the waveguide and used in the chip.

On-chip broadband light source

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.
