摘要： An integrated wavelength-selective filter device comprises a first optical element, for directing received radiation into a direction defined by a first angle, and a second optical element being a diffractive element configured for diffracting the directed radiation under a second angle. The second angle is such that for a single reference wavelength the diffracted radiation is directed into a propagation medium for advancing therein towards a predetermined position on the first optical element or on a further optical element for filtering radiation having a wavelength substantially matching the reference wavelength from radiation having a substantially different wavelength. The propagation medium is formed from a material that is different from any material of the substrate of the first and the second optical element.

摘要： A system for selectively adiabatically coupling electromagnetic waves from one waveguide to another waveguide is described. It comprises a first waveguide portion and a second waveguide portion having substantially different surface normal cross-sections. Portions thereof are positioned with respect to each other in a coupling region so that under first predetermined environmental conditions coupling of electromagnetic waves between the first waveguide portion and the second waveguide portion can occur and under second predetermined environmental conditions substantially no coupling of electromagnetic waves between the first waveguide portion and the second waveguide portion can occur. The system also comprises a fluid positioning means for selectively positioning at least a first fluid simultaneously overlaying both said first waveguide portion and said second waveguide portion in the coupling region thus selectively inducing first predetermined environmental conditions or second predetermined environmental conditions.

摘要： 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.

摘要： A method and device for detecting the presence of an unbound portion of therapeutic agents in a bodily fluid sample provided in which the bodily fluid includes an endogenous component of geometrical size larger than the therapeutic agent. A photonic integrated circuit has a porous material enrichment layer, a waveguide formed in the enrichment layer, and a blocking means provided on an outer surface of the enrichment layer. The enrichment layer with blocking means is permeable to the unbound therapeutic agent and prevents penetration of the endogenous component into pores of enrichment layer. The blocking means is configured to cooperate with the enrichment layer to maintain therapeutic agent access to the pores of the enrichment layer and prevent light-matter interaction between the at least one endogenous component and light guided in the waveguide, when contacting the liquid sample with the photonic integrated circuit.

摘要： A temperature compensation method for wavelength monitoring using spectrometers on photonic integrated chips and a related temperature-compensated wavelength monitoring device include an optical filter of the chip filters a source signal to provide at least one spectral reference line to a first spectrometer to detect thermal wavelength drifts thereof. At least one spectral line to be monitored is received by the same or another spectrometer of the chip to detect wavelength shifts thereof. The detected thermal drift of the reference line is compared to calibrated thermal drifts for the reference line which is associated with a calibrated thermal drift for the spectral response curve of the spectrometer receiving the spectral line to be monitored. A thermal drift rate for the response curve of the optical filter differs from a thermal drift rate for the response curve of the first spectrometer at least by an amount.

摘要： 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.
