摘要： An athermal mux/demux device comprising an AWG with a Mach-Zender apparatus optically coupled to an input side thereof. The Mach-Zender apparatus has first and second sides, the first side being optically coupled to an input waveguide of the device and the second side comprising two output ports optically coupled to an input side of the first slab waveguide of the AWG. The Mach-Zender apparatus is configured so that its temperature sensitivity substantially compensates for the temperature sensitivity of the AWG whereby the device is substantially athermal. In one embodiment one arm of the Mach-Zender has a portion of its length made of a polymer material, this portion being deigned such that the rate of change of effective refractive with temperature (dn eff /dT) of this polymer waveguide portion is of negative sign.

摘要： Various methods are described for reducing chromatic dispersion in planar optical waveguide device incorporating multi-mode waveguides. One method proposes choosing a shape of multi-mode waveguide for exciting at least one higher order mode above the fundamental mode, the shape being a function of at least one variable parameter; and optimizing one or more of the variable parameters so as to minimize chromatic dispersion in the device. The method can be used, for example, to optimize the shape of a multi-mode waveguide (6) provided in an AWG device (1), for flattening the output passband of the AWG. The variable parameter(s) can be, for example the length or width of one or more portions of the multi-mode waveguide. In one embodiment a phase-shifting waveguide (22) is disposed on one of a passband flattening multi-mode waveguide (20) in AWG and the length (L2) of the phase-shifting waveguide (22) is optimized to minimise chromatic dispersion.

摘要： A 1 x 2 splitter design having low loss is described. The splitter has a non-adiabatic tapered waveguide (22) connected between a substantially single-mode input waveguide (20) and two output waveguides (24, 26). The non-adiabatic tapered waveguide widens in width towards the output waveguides, and merges substantially continuously with the input waveguide in a direction parallel to the optical axis of the input waveguide. This keeps radiation mode generation to a minimum which, in turn, keeps insertion loss low. In the described embodiment, the non-adiabatic taper shape is based on a perturbed cosine function. The 1 x 2 splitter can be cascaded with other such splitters in order to build a 1 x 2N splitter design.
