摘要： A method for manufacturing an optical device with a defined total device stress and a therefrom resulting defined birefringence and a therefrom resulting defined optical polarization dependence is disclosed. In a preferred embodiment, a lower cladding layer of an amorphous material with a first refractive index is provided and above that an upper cladding layer of an amorphous material with a second refractive index, which latter is manufactured from a material which is tunable in its stress. Between the lower and upper cladding layer an optical waveguide core is manufactured comprising an amorphous material having a third refractive index which is larger than the first and second refractive index. The optical waveguide core is thermally annealed, after which it has a defined waveguide core stress. The upper cladding layer is manufactured to have a cladding layer stress that together with the waveguide core stress results in the total device stress.

摘要： An optical device with a defined total device stress (&sgr;10) and a therefrom resulting defined birefringence in order to obtain a well defined optical polarization dependence is proposed. It comprises a lower cladding layer (3) with a first refractive index (n3), thereon an upper cladding layer (5) with a second refractive index (n5) and between an optical waveguide core (4) with a third refractive index (n4) which is bigger than the first refractive index (n3) and the second refractive index (n5). The optical waveguide core (4) has a waveguide core stress (&sgr;4) resulting from the manufacturing process and the upper cladding layer (5) is manufactured to have an inherent cladding layer stress (&sgr;5) which together with the waveguide core stress (&sgr;4) results in the total device stress (&sgr;10).

摘要： An electrically adjustable phase-shifting device is arranged on a substrate comprising at least a first waveguide designed for guiding optical signals and a thermoelectric element arranged adjacent to the first waveguide in order to shift the phase of an optical signal in the first waveguide by means of a thermo-optic effect according to a control voltage applied to the thermoelectric element. In one embodiment, the thermoelectric element is a Peitier element which comprises at least first and second electrically conducting segments which are serially connected, the first and second elements alternating consecutively.

摘要： A method for manufacturing an optical device with a defined total device stress, birefringence and optical polarization dependence is disclosed. The method comprises first providing a tower cladding layer of an amorphous material with a first refractive index and then providing above the lower cladding layer an upper cladding layer of an amorphous material with a second refractive index. An optical waveguide core comprising an amorphous material having a third refractive index (larger than the first refractive index and the second refractive index) is provided between the lower and the upper cladding layers. The upper cladding layer is thermally annealed by keeping the upper cladding layer at a first temperature, then raising the temperature to a second temperature, maintaining the second temperature for an annealing time period, and lowering the temperature to a third temperature, after which the temperature is lowered to a fourth temperature.
