Fiber-Coupling Lens Design and Tolerance Analysis
In many fiber-optics systems, a customized design of the coupling lens is often required so as to achieve a good fit with the given input field and working distance. VirtualLab provides not only the tools for the analysis of fiber-coupling efficiency, with the in-built Parametric Optimization function, but also enables an efficient design of the coupling lenses. In fiber optics, it is also known that coupling efficiency may be sensitive to e.g. misalignment of the components in the system. With the Parameter Run in VirtualLab, one can conveniently perform a tolerance analysis of such fiber-coupling systems and investigate the influence of different parameters.
Parametric Optimization of Fiber-Coupling Lenses
We present the design of a fiber-coupling lens with conical surface, for the purpose of efficient light coupling into a single-mode fiber, using parametric optimization in VirtualLab Fusion.
Tolerance Analysis of a Fiber-Coupling Setup
In a fiber-coupling optical setup, the coupling efficiency is analyzed with respect to different tolerance factors like the shift of the position of the fiber end and the tilt of lens.

Performance Evaluation of Fiber-Coupling Systems
Optical fibers are widely used in different applications; single-mode fibers especially play an important role in long-distance communications. Launching light into single-mode fibers can be a challenging task in practice. VirtualLab Fusion enables fast evaluation of fiber-coupling systems thanks to the physical-optics-based simulation techniques, fiber-related detectors, and many other helpful tools. For example, one can find the optimal working distance for coupling light into single-mode fibers, and compare the performance of different coupling lenses.
Optimal Working Distance for Coupling Light into Single-Mode Fibers
In this example, we select one commercially available lens and show how to find the optimal working distance to obtain maximum fiber-coupling efficiency using field tracing.
Comparison of Different Lenses for Fiber-Coupling
For the task of coupling light into a single-mode fiber, two commercially available lenses are selected and their performance is evaluated using the overlap integral.

LightTrans awarded with i-work-Business Award 2018
The LightTrans International UG has been awarded with the “i-work Business Award” in the category “SME - small and medium-sized enterprises” on 27 November 2018 in Jena, Germany. LightTrans employs 25 employees, thereof 40 percent are international specialists originated from 8 different countries. This international workforce results in intercultural opening and collaboration in the company.
“We are an internationally oriented company with heart and soul. With our efforts and experiences, we aim to increase the visibleness of the topics integration in the corporate landscape of Jena and its region.”, emphasizes Petra Wyrowski, co-founder and shareholder.
The jury of the award for intercultural diversity in Jena was convinced by LightTrans’ extensive company concept. International employees are not only supported during their starting time in Germany, e.g. administrative matters or their apartment search. Especially the togetherness in LightTrans’ working life is focused on cultural diversity: in the office speaking German and English is a matter of course. Experiencing time together, like corporate excursions, taking part in sporting events or games night complement the concept. Additionally an intensive cooperation with the “Abbe School of Photonics” - an optical and photonics oriented education program at Friedrich-Schiller-Universität Jena addresses international students already in the academic environment.
“We value the versatile cultural influences and perspectives of our international specialists, who clearly improve and promote our work and company.” Adds Michael Höschel, Managing Director of LightTrans.
i-work Business Award
The i-work Business Award is awarded by the Business Development Agency Jena and the prestigious Friedrich Schiller University Jena under the patronage of employment minister Heike Werner. The award honors companies which promote intercultural opening for international professionals exemplary. The i-work is part of the project „HiTh–Hochqualifiziert. International. Thüringen.“ supporting international concepts of companies in Jena and its region.
