摘要： 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.

摘要： A new blue extended super continuum light source is claimed. When pulses of partly coherent monochromatic "pump" radiation of essentially constant amplitude is 5 propagating through a microstructure fibre medium within a region of anomalous dispersion of the medium, then, provided the medium has a finite nonlinear coefficient of the index of refraction, the pump pulse is subject to a modulation instability. This instability results in the generation and exponential growth of sidebands, the two closest to the "pump" frequency being the dominant ones. The 10 modulation frequency is proportional to the square root of the power in the carrier wave. In the time domain this leads to that the interaction between the medium and the radiation results in contraction of the width of the amplitude peaks, which results in formation of a train of narrow pulses with Tera Hertz repetition rate. 15 Phase match between red shifted Raman solitons generated by the pump pulse and energy shed by the pump pulse at all frequencies with a group velocity below the pump pulse group velocity will lead to the formation of Cherenkov radiation. The solitons or "light bullets" will seed Cherenkov radiation in the near infrared, visible or at UV wavelengths depending on the actual fibre parameters. This extends the 20 generated super continuum light beyond the four wave mixing limit usually experienced when applying picoseconds or nanoseconds pump pulses.

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.

摘要： A high power amplifier silica glass material is provided wherein photo darkening due to high optical flux is reduced considerably. The conventional counter part amplifier and laser based on conventional silica glass material have a problem in that their characteristics are deteriorated with the elapse of time due to photo darkening. The new fibre amplifier and laser silica glass material shows through reduction of the non-binding oxygen electron concentration less photo darkening. This is achieved through hydrogen or deuterium load of the amplifier glass material or by co-doping with phosphorous P 4 O 8-x (OH) 4+2x , (0 x 2).
