title: Imprinted bidirectional waveguide platform for large-core optical transceiver.
abstract: 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.
