- AI demands lower numerical precision (4-8 bits for inference), reducing accuracy requirements and energy costs for photonic computation.
- Thermal engineering advancements are addressing MZI sensitivity: athermal designs with materials like silicon and silicon nitride, integrated heaters for stability, and thermal undercut techniques.
- Vapor chamber cooling from smartphones may provide uniform temperature control, lowering stabilization overhead for photonic chips.
- AI's energy consumption crisis creates economic pressure to adopt energy-efficient photonic alternatives for matrix multiplication.
- Despite progress, challenges remain including analogue noise, memory integration, manufacturing yields, and hybrid system inefficiencies.
