摘要： The invention relates to a conventional broad-area laser having a single-mode output through the phenomenon of multimode interference (MMI) in step-index waveguides. Another aspect of the present invention relates to a very robust multi-mode compound cavity laser design that is fully defined by the geometry and the refractive index profile of the MMI region, which is quite insensitive to slight macro-scale refractive index variations due to manufacturing variation or temperature. As the self-imaging position shifts linearly in the refractive index, the confocal beam parameter can be made relatively long.

摘要： An integrated optical arrangement operated as a switch composed of at least three ridge waveguides on a substrate, the third ridge waveguide is utilized for an infeed of an optical waveguide proceeding between two parallel ridge waveguides forming the first and second waveguides having either a contacted pn-junction or a contacted pin-junction. As a result of asymmetrical switching of the junctions, the optical wave is coupled over into one or the other of the first and second waveguides. The advantage over traditional directional coupler switch structures are complete symmetry of the two switch conditions, "digital switching behavior", enhanced separation of the output waveguide, low switching losses and greater manufacturing tolerances, reduced polarization sensitivity and increased optical bandwidth.

摘要： A Lyot depolarizer for depolarizing a laser with multiple longitudinal modes comprises two segments of PM fiber optimized for length as a function of the longitudinal mode spacing of the laser source, and not as taught in the prior art as a function of the laser coherence length. The present invention has found secondary coherence peaks in the coherence function of a multiple longitudinal mode source, which can significantly worsen the DoP if the PM fiber lengths are significantly extended beyond optimum, contrary to the teaching in the prior art. The present invention makes use of the periodic structure of the source spectrum by converting half the longitudinal modes to an orthogonal polarization state. As a result a significantly shorter fiber depolarizer is needed than for a single longitudinal mode source. Greater temperature stability is achieved by properly adjusting the lengths of both segments of PM fiber.
摘要翻译：用于对具有多个纵向模式去激光的Lyot去极化器包括针对作为激光源的纵向模式间隔的函数的长度优化的两段PM光纤，并且不像现有技术中作为激光相干长度的函数所教导。本发明已经发现多纵向模式源的相干函数中的二次相干峰值，与现有技术中的教导相反，如果PM光纤长度显着延伸超出最佳值，则可以显着恶化DoP。本发明通过将纵向模式的一半转换为正交偏振状态来利用源光谱的周期性结构。因此，对于单个纵向模式源，需要明显更短的纤维去极化器。通过适当调整PM纤维两段的长度可实现更高的温度稳定性。

摘要： A configuration for triggering a restraining device has firing elements that are optically fired by an associated triggering device. In addition, an optical check signal can be transmitted to the firing element by the triggering device. An evaluation circuit evaluates light signals that have been transmitted to the triggering device. As a function of an evaluated, received light signal, a disable signal, by which emission of a firing signal is prevented, is generated by the evaluation circuit.
