Resumen:
Una universidad alemana ha desarrollado una solución para mejorar la calidad de señal entre guías de onda ópticas de diferente espesor. El ajuste individual del ángulo, anchura de paso y longitud permite reducir las pérdidas de transmisión o evitarlas (casi) completamente. La nueva solución se basa en la conclusión de que puede conseguirse un incremento en la eficiencia con una fase intermedia en la transición de las dos guías de onda ópticas. Esta fase intermedia no es perpendicular a la dirección de propagación de la luz, sino oblicua. La universidad busca socios en el campo de óptica integrada con el fin de establecer acuerdos de licencia o cooperación técnica.

Tittle:
Low-loss transition between optical layer waveguides of different thicknesses
Summary:
A German university developed a solution to improve the signal quality between optical layer waveguides. By individually adjusting the angle, step width and height, it is possible to minimize the transmission losses, or (almost) completely avoid them. The university offers a license agreement and a technical cooperation agreement.
Description:
In transitions between dielectric optical waveguides of different thickness, modal mismatch usually causes radiation losses and optical backscatter. Taper structures, which can produce a gradual, quasiadiabatic transition between the waveguides with different thicknesses, can help here. However, tapering structures of this kind are generally complicated to design and manufacture. In addition, these structures are usually relatively large in relation to typical dimensions of integrated-photonic components.

A German university has set itself the task to address this issue. The university developed a solution that makes an efficient, low-loss transition between two optical layer waveguides of different thicknesses possible.
The novel solution is based on the finding that an efficiency gain can be achieved with an intermediate stage at the transition of the two optical waveguides. This intermediate stage does not run perpendicular to the propagation direction of the light, but obliquely. By individually adjusting the angle, step width and height, it is possible to minimize the transmission losses, or (almost) completely avoid them.

The university offers a license agreement and a technical cooperation agreement to companies working in the field of integrated optics. In both types of cooperation, the potential partner is responsible for the further development to market maturity. In the case of a technical cooperation, the university offers professional support.
Advantages and Innovations:
The innovation of the method presented here lies in the fact that the signal quality of optical waveguides is improved and transmission losses are minimized. In addition, it has a simple design and has compact dimensions. Furthermore the production is cost-effective.
