Title: The Innovations of Olaf Hildebrand
Introduction
Olaf Hildebrand is a notable inventor based in Stuttgart, Germany. He has made significant contributions to the field of optical technology, holding a total of 7 patents. His work primarily focuses on optical coupling arrangements and semiconductor devices.
Latest Patents
Hildebrand's latest patents include an optical coupling arrangement that features an optical duplexer configured as a directional coupler. This innovative design integrates a fiber optic pigtail constructed in planar-optical hybrid technology on a substrate. To minimize the required surface area and reduce optical cross talk, the directional coupler's branch is sharply bent, equipped with a reflecting mirror integrated opposite the inner edge of the bend. Additionally, the waveguiding end of the bent branch is fitted with a cylindrical lens, with a laser diode positioned before it and a photodiode located before the angled end of the straight-line integrated waveguide.
Another significant patent involves a method of operating a semiconductor device as an optical filter. This semiconductor device features a substrate and a monolithically integrated branched waveguide structure. Portions of the waveguide structure are divided into multiple regions by troughs, with one region serving as a branching area. Light is introduced into the waveguide structure at the end face of one of the regions, while currents smaller than the respective laser threshold currents flow through the regions, including the branching region, perpendicular to the light's propagation direction.
