What is NeuroCircuit?
The operational concept of NeuroCircuit closely mimics the function of the “neuron system.” The system begins with the dendrite (Connector), which receives electrical signals and transmits them to the cell body and hillock (Tx, Transmitter), where the signals are converted into optical signals. These optical signals are transmitted through the axon and myelin (Waveguide) to the axon terminal (Rx, Receiver), completing the continuous and high-speed transmission of signals involved in sensory stimulus reception, information integration, and pulse conduction.
The architecture of NeuroCircuit
The FPC-based optoelectronic module (NeuroCircuit™) consists of three main components:
- Optical components (optical ICs and chips)
- LCP-based electrical FPC
- Polymer-based optical waveguide
Each component plays a critical role in signal transmission. The optical components handle optical signal conversion, the FPC carries electrical signals, and the embedded optical waveguide guides light through the module from Tx to Rx.
This architecture enables a thinner, more flexible, and lightweight form factor, supporting high-density integration for high-bandwidth applications.

Ultra-Thin Bottom-Emission VCSEL-Based Optoelectronic Flexible Printed Circuit Module for High-Speed Transmission
With the growing demand for high-bandwidth applications in consumer electronics, higher data rates are required for interfaces such as USB, Thunderbolt, PCIe, HDMI, and MIPI. At the same time, increasing circuit density in compact mobile devices leads to greater electromagnetic interference (EMI) and signal degradation.
Although conventional FPCs offer advantages such as flexibility, thinness, and low cost, achieving high-speed and low-noise transmission still requires multilayer structures and thicker dielectric layers. To address these limitations, this work proposes Active Optical Waveguide (AOW) embedded FPCs, which transmit signals through optical waveguides to reduce EMI and transmission loss while decreasing multilayer thickness by more than 65%, enabling ultra-thin and high-performance interconnects.
