Example of a Full Adder Photonic Chip Structure:
This design is based on a full adder, completely transforming traditional electronic circuitry into a 45-degree optical path architecture. To demonstrate the three-dimensional integration capabilities of photonic chips, the original planar structure is further optimized into a three-layer stacked design:
Top Layer : Optical Path Layer
Middle Layer : Logic Gate Layer
Bottom Layer : Memory Layer
The entire fabrication process utilizes three different photomasks.
Compared to electronic chips that often require dozens of layers, photonic chips can achieve high-efficiency computation with only three layers. Combined with photonic memory, its computational performance can be increased by hundreds of thousands of times. Because light completes access at near-instantaneous speeds, its actual speed is difficult to measure accurately using traditional methods.
