We introduce a new configuration for large-core optical transceiver platforms based on asymmetric three-dimensional multimode Y junctions. We developed a simply structured bidirectional waveguide platform without using a wavelength division multiplexing filter or angled mirror. This structure was designed with two different size waveguides by using the three-dimensional ray-tracing method. This structure transmitted nearly 100% power in each direction, upstream and downstream. This simple and cost-effective structure was fabricated by the imprint process using a metallic master fabricated by an ultraprecision machining method. The experimental results show that this structure is suitable for bidirectional communications in large-core optical transceivers at 155 Mbits/s.
我们提出了一种基于非对称三维多模 Y 结的新型大芯径光收发器平台结构。我们开发了一种结构简单的双向波导平台，无需使用波分复用滤波器或倾斜反射镜。该结构通过三维光线追踪方法设计了两个不同尺寸的波导。该结构在上下行方向上每个方向都传输近 100%的功率。这种简单且具有成本效益的结构是通过压印工艺制造的，使用超精密加工方法制造的金属母版。实验结果表明，该结构适用于 155 Mbits/s 的大芯径光收发器中的双向通信。
