20100133639 | Photosensitive Semiconductor Component - A semiconductor component that includes a photosensitive doped semiconductor layer, in which electrical charge carriers are released during absorption of electromagnetic radiation is disclosed. The photosensitive semiconductor layer has a structured interface and at least one layer which generates an electric field for separating the released charge carriers disposed downstream of the structured interface. The electric field extends over the structured interface. The photosensitive semiconductor component is distinguished by a high efficiency of the charge carrier separation, in particular, for generating an electric current. | 06-03-2010 |

20110286479 | Pulsed light source - It is an object of the present invention to provide a compact and low-cost system for generating ultra short high energy laser light pulses that does not use the known CPA scheme. The proposed approach is based on spectral filtering of laser light pulses of a mode locked laser source. The used mode locked laser source can be of any kind as long as its filtered residual pulse bandwidth supports pulse durations longer than 20 ps and up to 1 ns. After filtering the laser light pulses are directly amplified in an amplification element consisting of one or more amplification stages. At the same time or just after amplification the light pulses are spectrally broadened through a spectral broadening element, for example a fiber of suitably chosen core diameter and length to achieve a spectral bandwidth that is wide enough to support sub 10 ps pulses. Finally, the spectrally broadened laser light pulses are compressed by a compact dispersive element consisting of one or more Bragg gratings or a grating pair. | 11-24-2011 |
20120069428 | SINGLE-MODE PROPAGATION IN MICROSTRUCTURED OPTICAL FIBERS - The invention relates to an optical fiber as an optical waveguide for the single-mode operation. The present invention proposes a fiber having a microstructure, by which the propagation of modes of a higher order are selectively suppressed in the optical waveguide. At the same time, the propagation of transversal modes of a higher order is dampened more strongly than the propagation of the fundamental modes of the optical waveguide. | 03-22-2012 |
