Traditional electronic interconnects rely on electron drift velocity, which is inherently limited by resistance and capacitance, leading to significant thermal dissipation and latency at high densities. This fundamental physical constraint dictates the maximum compute throughput in conventional silicon architectures.
In contrast, optical waveguides transmit data as photons at the speed of light, bypassing electron-based thermal degradation entirely. This enables sub-nanosecond latency and massive bandwidth density, unlocking unprecedented performance for tensor workloads through wavelength division multiplexing.
Four-Stage Light Lifecycle for Photonic Processing
Laser Emission
Electro-Optic Modulation
Waveguide Transport
Photodiode Capture
Precise on-chip laser sources generate coherent light, initiating the data transmission cycle within the integrated photonic circuit.
Electrical signals are converted into optical data streams by modulating the light's amplitude or phase, encoding information onto photons.
Modulated light travels through ultra-low-loss silicon optical waveguides, ensuring high-fidelity, high-speed data transfer across the chip.
At the destination, integrated photodiodes convert the optical signals back into electrical form for processing by subsequent electronic stages.
