Development of micro-optical components and coupling structures in thin polymer foils using hot embossing (B04)

B04专注于利用热压印和刀刃技术实现单模波导和传感器结构。这些元件将用于开发多层功能化传感薄膜。我们还继续朝着制造过程的卷轴到卷轴的实施迈出第一步。为了有效地连接相干/非相干光源和光探测器以及提供光网络元件，我们将实现基于新的双波长自写入波导方法的耦合结构和网络组件，以及为单模光学元件和特定光学模式耦合而设计的光栅和消失场耦合器。

B04 focuses on the realization of single-mode waveguides and sensor structures utilizing hot embossing and doctor blading. These components will be employed to develop multi-layer functionalized sensing foils. We also pursue first steps towards a reel-to-reel implementation of the fabrication process. To efficiently connect coherent/incoherent light sources and photodetectors as well as to provide optical network elements, we will realize coupling structures and network components based on a novel 2-wavelength self-written waveguide approach, as well as grating and evanescent field couplers both designed for single-mode optical elements as well as for coupling to specific optical modes.
