    Abstract: Optically coherent, two-port, serially cascaded-form optical delay line circuits can realize arbitrary signal processing functions identical to those of FIR digital filters with complex filter coefficients whilst maintaining a maximum optical transmission characteristic of 100%. The invention provides an iterative process for transitioning in a step-wise manner a filter function of an optical delay line circuit filter from a start filter function to a target filter function. The invention also describes a dynamic gain equalizer incorporating an optical delay line circuit filter.

    Abstract: A method of inducing phase changes in a FIR filter is provided. The FIR filter consists of a concatenation of tunable couplers and tunable delay lines made of planar waveguides fabricated in SiON technology, forming a plurality of interferometers, at least one of which carries a heater on at least one of its waveguide arms. The method includes the step of exposing at least one of the arms of the interferometers to an irradiation at UV or a smaller wavelength, thereby inducing a change in the refractive index of the waveguide arms which induces the phase difference change. The method provides a procedure that will lead to temperature-stable changes of the refractive index of the waveguides. The resulting device is temperature-stable such that it can be afterwards be heated with chromium heaters to dynamically tune its spectral response without destroying the UV-induced changes.

    Abstract: 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.

    Abstract: An electro-optical module comprising flexible connection cable and aligning capabilities is disclosed. Electro-optical devices may be soldered on a transparent substrate such as glass or a substrate comprising an optical waveguide wherein electrically conductive traces are designed, forming an electro-optical module. When such electro-optical module is inserted and aligned into a printed circuit board, the external part of the substrate, comprising electrically conductive traces and pads, referred to as flex-cable, is bent down toward the mounting plane of the PCB allowing to establish electrical connections between these pads and the PCB. The substrate may be broken along a pre-formed groove, and the external part of the substrate can be removed leaving the flex-cable section in place.
