摘要:
A component to be used for the frequency-selective modulation and/or for the frequency-selective receiving and demodulation of frequency-division multiplexed optical signals. The component of the present invention includes a waveguide, to which multiplexed optical signals are applied, and at least one further waveguide, running substantially parallel to the waveguide and which is evanescently coupled to the waveguide. The at least one further waveguide is designed as a Bragg resonator, by means of a structuring in the longitudinal direction, and the component further includes at least one semiconductor diode, which is optically coupled to the Bragg resonator.

A light-emitting diode arrangement comprises a sub-mount on which a light-emitting diode chip is mounted, and a reflector which is adjusted at the sub-mount and has a reflector surface located in the beam path of the light-emitting diode chip. The reflector is formed from the lateral wall of a solid body consisting of a transparent material and having a small irradiation surface located opposite the light-emitting diode chip (3) and a large radiation surface which is located opposite the same, at a distance, a lateral wall forming a reflector surface extending therebetween, and the sub-mount comprises an opening into which the reflector body is inserted, with the irradiation surface first.
摘要:
A method for producing a cover for an integrated optical circuit, and an integrated optical circuit produced with this cover. The method minimizes the effort for the integration of optical components into fiber-optic systems by automatically positioning an optical component placed onto a mold punch. A liquid that can harden is poured around the optical component and the mold punch, and after this solidifies, it forms the cover.

摘要:
To planarize an electroformed, magnetic metal sheet having micropatterns, the metal sheet is clamped on a magnet and is mechanically processed on the back side of the metal in such a way that it assumes a plane-parallel shape. Metal sheets can be used which are not stress-free and are obtained in a fast electroplating process. Multiple copying is possible.

摘要:
For the shaping of a microstructure substrate via a mold cavity, an unmolding device allows an abrupt, shear-free separation, in particular at reaction temperature, of the microstructure substrate manufactured using the reaction molding method. Optical waveguide components meeting stringent damping requirements can easily be manufactured with this device.
摘要:
An integrated optical component is proposed, which has an optical component coupled to a waveguide. A buffer layer is provided for improving the coupling. The integrated optical component is produced with the aid of molding techniques. In the process an optical component is placed on a molding die and is adjustedly arranged on a waveguide by means of adjusting tabs. Following molding and removal of the molding die, the optical component is disposed, adjusted in respect to a waveguide, in a substrate plate. The waveguide is filled with a polymer and covered with a cover plate.
