The problem is solved in that the coupling part (3) comprises a) at least one elongate groove (32) in the form of a recess in the waveguide face, the groove being adapted to receive an elongated optical application waveguide (41), and b) at least one coupling waveguide (31) and at least one groove (32) are formed on the coupling-substrate (30) relative to each other so that the output face of the coupling waveguide is suitable for being side-coupled to an application waveguide (41) located in said groove. The invention further relates to a light source part and a light source module and to optical devices based on these parts. The invention may e.g. be used in high power fibre lasers or fibre amplifiers.

Abstract: An optical structure (10, 100, 150) for surface-enhanced spectroscopy based on surface plasmons (SP). The structure comprises a plurality of layers (11) with SP-active sites, and the plurality of layers (11) is optically arranged so as to allow direct access for a target analyte (T) into and/or onto the plurality of layers. This optical structure is advantageous for obtaining optical sensitivity that may be increased by essentially going from a two-dimensional (2D) optical structure, as known in the prior art, to a three-dimensional (3D) optical structure.

Abstract: The invention relates to an optical waveguide for guiding light in a predefined wavelength range, the optical waveguide comprising core and cladding regions for confining light, the core and/or cladding region or regions being formed on a substrate and comprising material of the stoichiometric composition Si a O X N y X z H v . The invention further relates to a method of manufacturing an optical waveguide, an optical waveguide obtainable by the method and an optical device comprising such a waveguide. The object of the present invention is to provide an optical waveguide with low optical loss due to a reduced hydrogen bond-originated absorption. The problem is solved in that X is selected from the group of elements B, AI, P, S, As, Sb and combinations thereof, and the ratio y/z is larger than 1. This has the advantage that a low optical absorption in the waveguide may be achieved, possibly over a broad wavelength range. Further, a relatively low annealing temperature may be used yielding a relatively low induced strain whereby a low birefringence may be achieved. The optical waveguide may e.g. be manufactured by PECVD, which is ideal for the further processing of low loss waveguides. Waveguides according to the invention show superior transmission characterized with losses below 0.05 dB/cm between 900 nm and 1600 nm. In particular the absorption due to the second overtone of the Si:N-H vibration may be lowered to a value below the detection level. The invention may e.g. be used for the optical communications systems, in particular for branching components (e.g. splitters) and components for wavelength division multiplexing (WDM) systems, e.g. telecommunication systems, fibre-to-the-home, etc.
